Installation & Operation Manual

Introduction
Congratulations on the purchase of the new P9 Adjustable Speed Drive!
The P9 Adjustable Speed Drive (ASD) is a solid-state AC drive that features Toshiba International
Corporation’s (TIC) new Virtual Linear Pump function. The VLP algorithm was designed to remove
the guess work that is associated with the setup of pumping systems. The VLP algorithm allows for
precise, linear, and consistent pump curve responses at any flow or pressure setting!
The Virtual Linear Pump function allows for direct and precise pumping system control. This is
accomplished without the normal concerns of the adverse effects of conventional pumping system
control response curves.
Toshiba’s VLP algorithm is further enhanced by the introduction of the new Time-Based Alternation
(TBA) function! Time-Based Alternation optimizes load sharing and offers a significantly decreased
level of system down-time.
Time-Based Alternation provides a more evenly-spread machine wear pattern for all motors and
pumps of the system. Load sharing is optimized by allowing all pumps to alternate as the primary pump
while the remaining pump(s) operate in an ancillary mode for time intervals that are determined by the
user.
The decreased system down-time is realized in the event of a failure of one or more pumps, when
seamlessly, the system continues to operate, albeit with a diminished capacity.
Using VLP and Time-Based Alternation, the system seamlessly and easily adapts to peak load
demands while maintaining the same degree of high performance and reliability output across the entire
load range - without any user intervention!
The VLP and Time-Based Alternation algorithms coupled with Toshiba International Corporation’s
Vector Control Algorithm provides setup ease, enhanced reliability, and precise control under the most
demanding conditions. All while enabling the motors of the system to develop high starting torque and
provide compensation for motor slip, which results in smooth, quick starts, and highly efficient
operation.
The programmable functions may be accessed via the easy-to-use menu or via the Direct Access
Numbers (see pg. 81). This feature, combined with Toshiba International Corporation’s high-
performance software, delivers unparalleled motor control, reliability, and ease of use.
The P9 is a very powerful tool, yet surprisingly simple to operate. The user-friendly Electronic
Operator Interface (EOI) of the P9 has an easy-to-read LCD screen. There is also a high-visibility
LED screen that can be read from a greater distance. The EOI provides easy access to the many
monitoring and programming features of the P9.
To maximize the abilities of your new P9, a working familiarity with this manual is required. This
manual has been prepared for the ASD installer, user, and maintenance personnel. This manual may
also be used as a reference guide or for training. With this in mind, use this manual to develop a
familiarity with the P9 before attempting to install, operate, or perform maintenance on the device.

Conductor Routing and Grounding
Precautions
• Use separate metal conduits for routing the input power, output power, and control circuits.
• A separate ground cable should be run inside the conduit with the input power, output power, and
control circuits.
•DO NOT connect CC to earth ground.
•UseIICC terminal as the return for the V/I input.
• Always ground the unit to prevent electrical shock and to help reduce electrical noise.
• If the ASD is being used in an ungrounded system (floating system) or in an asymmetrically
grounded system, the EMI filter must be disconnected or removed. The ASD may be damaged if
the EMI filter is used.
• It is the responsibility of the ASD installer/maintenance personnel to provide proper grounding and
branch circuit protection in accordance with the NEC and any applicable local codes.
— The Metal Conduit Is Not An Acceptable Ground —
Grounding Capacitor Setting Precaution
If operating using an ungrounded 3-phase power source or within a high-resistance grounding
system, the Grounding Capacitance must be set to Small or Out (typeform-specific) as
shown on pg. 19. If set to High, a system malfunction, component failure, or fire may result.
Grounding Capacitor Switching
The ASD is equipped with noise reduction capacitors which are used to reduce the EMI leakage via the
3-phase power-input circuit and for compliance with the Electromagnetic Compatibility Directive
(EMC).
The effective value of the capacitor may be increased, reduced, or removed entirely via the Selector
Switch, Switching Bar, or the Switching Screw — the type used is typeform-specific.
The Grounding Capacitor Switch allows the user to quickly change the value of the capacitance of the
3-phase input circuit without the use of tools. The Switching Bar and the Switching Screw are easily
changed with the use of a wrench or a screw driver, respectively.
See the section titled System Grounding on pg. 18 for more on the Grounding Capacitor.
See figures 4, 5, 6, and 7 on pg. 19 for an electrical depiction of the leakage-reduction functionality of
the Grounding Capacitor and the methods used to set the capacitance value.

DANGER

P9 ASD Installation and Operation Manual 7
System Integration Precautions
The following precautions are provided as general guidelines for the setup of the ASD within the
system.
• The TIC ASD is a general-purpose product. It is a system component only and the system design
should take this into consideration. Please contact your TIC Sales Representative for application-
specific information or for training support.
• The TIC ASD is part of a larger system and the safe operation of the ASD will depend upon
observing certain precautions and performing proper system integration.
• Improperly designed or improperly installed system interlocks may render the motor unable to start
or stop on command.
•The failure of external or ancillary components may cause intermittent system operation (i.e., the
system may start the motor without warning).
• A detailed system analysis and job safety analysis should be performed by the systems designer
and/or systems integrator before the installation of the ASD component. Contact your TIC Sales
Representative for options availability and for application-specific system integration information
if required.
Personnel Protection
• Installation, operation, and maintenance shall be performed by Qualified Personnel ONLY.
• A thorough understanding of the ASD will be required before the installation, operation, or
maintenance of the ASD.
• Rotating machinery and live conductors can be hazardous and shall not come into contact with
personnel. Personnel should be protected from all rotating machinery and electrical hazards at all
times.
• Insulators, machine guards, and electrical safeguards may fail or be defeated by the purposeful or
inadvertent actions of workers. Insulators, machine guards, and electrical safeguards are to be
inspected (and tested where possible) at installation and periodically after installation for potential
hazardous conditions.
•DO NOT allow personnel near rotating machinery. Warning signs to this effect shall be posted at or
near the machinery.
•DO NOT allow personnel near electrical conductors. Contact with electrical conductors can be
fatal. Warning signs to this effect shall be posted at or near the hazard.
• Personal Protection Equipment (PPE) shall be provided and used to protect employees from any

WARNING

8P9 ASD Installation and Operation Manual
System Setup Requirements
• With the exception of the TBA Pump Number (F434), ensure that all Time-Based Alternation
parameter settings and the real-time clock settings for each ASD within the system are the same.
• When using the ASD as an integral part of a larger system, it is the responsibility of the ASD
installer/maintenance personnel to ensure that there is a fail-safe in place (i.e., an arrangement
designed to switch the system to a safe condition if there is a fault or failure).
• Power factor improvement capacitors or surge absorbers MUST NOT be installed on the output of
the ASD.
• Use of the built-in system protective features is highly recommended (i.e., E-Off, Overload
Protection, etc.).
• The operating controls and system status indicators should be clearly readable and positioned
where the operator can see them without obstruction.
• Additional warnings and notifications shall be posted at the equipment installation location as
deemed required by Qualified Personnel.
• System safety features should be employed and designed into the integrated system in a manner
such that system operation, even in the event of system failure, will not cause harm or result in
system damage or injury to personnel (i.e., E-Off, Auto-Restart settings, System Interlocks, etc.).
• The programming setup and system configuration of the ASD may allow it to start the motor
unexpectedly. A familiarity with the Time-Based Alternation (F404), VLP Auto Start-Stop
(F385), Auto-Restart (F301), and the Sleep Timer (F383) settings are a requirement to use this
product.
• The setup procedures included within this manual may require a Reset before performing the
procedure. Application-specific settings may then be performed. The pre-Reset conditions may be
saved (see F007).
• There may be thermal or physical properties, or ancillary devices integrated into the overall system
that may allow for the ASD to start the motor without warning. Signs to this effect must be posted
at the equipment installation location.
• If a secondary magnetic contactor (MC) or an ASD output disconnect is used between the ASD and
the load, it should be interlocked to halt the ASD before the secondary contact opens. If the output
contactor is used for bypass operation, it must be interlocked such that commercial power is never
applied to the ASD output terminals (U, V, or W).
• When using an ASD output disconnect, the ASD and the motor must be stopped before the
disconnect is either opened or closed. Closing the output disconnect while the 3-phase output of the
ASD is active may result in equipment damage or injury to personnel.

• The heat sink and other components may become extremely hot to the touch. Allow the unit to cool
before coming in contact with these items.
•TheAuto Start-Stop and the Sleep Timer programmable functions of the ASD may allow for the
system to start or stop unexpectedly. Signs to this effect are to be clearly posted at the installation
location.
• Remove power from the ASD during extended periods of non-use.
• The system should be inspected periodically for damaged or improperly functioning parts,
cleanliness, and to ensure that the connectors are tightened securely.
DANGER

10 P9 ASD Installation and Operation Manual
Motor Characteristics
Listed below are some variable speed AC motor control concepts with which the user of the
ASD should become familiar.
Motor Autotuning
Motor production methods may cause minor differences in the motor operation. The negative effects of
these differences may be minimized by using the Autotune feature of the ASD. Autotuning is a function
of the ASD that measures several parameters of the connected motor and places these readings in a stored
table. The software uses the information in the table to help optimize the response of the ASD to
application-specific load and operational requirements. The Autotuning function may be enabled for
automatic tuning, configured manually at F400, or disabled.
The measured parameters include the rotor resistance, the stator resistance, the required excitation
inductance, rotational inertia values, and leakage inductance values.
Pulse Width Modulation Operation
The ASD uses sinusoidal Pulse Width Modulation (PWM) control. The output current waveform
generated by the ASD approaches that of a perfect sine wave; however, the output waveform is slightly
distorted. For this reason, the motor may produce more heat, noise, and vibration when operated by an
ASD, rather than directly from commercial power.
Low-Speed Operation
Operating a general-purpose motor at lower speeds may cause a decrease in the cooling ability of the
motor. Reducing the torque requirement of the motor at lower speeds will decrease the generated heat at
lower speeds.
When the motor is to be operated at low speed (less than 50% of full speed) and at the rated torque
continuously, a TIC VF motor (designed for use in conjunction with an ASD) is recommended.
Overload Protection Adjustment
The ASD software monitors the output current of the system and determines when an overload condition
occurs. The overload current level is a percentage of the rating of the motor. This function protects the
motor from overload.
The default setting for the overload detection circuit is set to the maximum rated current of the ASD at the
factory. This setting will have to be adjusted to match the rating of the motor with which the ASD is to be
used. To change the overload reference level, see Motor Overload Protection Level 1 on pg. 198.
Operation Above 60 Hz
A motor produces more noise and vibration when it is operated at frequencies above 60 Hz. Also, when
operating a motor above 60 Hz, the rated limit of the motor or its bearings may be exceeded; this may void
the motor warranty.
Contact the motor manufacturer for additional information before operating the motor above 60 Hz.

P9 ASD Installation and Operation Manual 11
Power Factor Correction
DO NOT connect a power factor correction capacitor or surge absorber to the output of the ASD.
If the ASD is used with a motor that is equipped with a capacitor for power factor correction, remove the
capacitor from the motor.
Connecting either of these devices to the output of the ASD may cause the ASD to malfunction and trip,
or the output device may cause an over-current condition resulting in damage to the device or the ASD.
Light Load Conditions
When a motor is operated under a continuous light load (i.e., at a load of less than 50% of its rated
capacity) or it drives a load which produces a very small amount of inertia, it may become unstable and
produce abnormal vibration or trips because of an over-current condition. In such a case, the carrier
frequency may be lowered to compensate for this undesirable condition (see Program Special 
Carrier Frequency PWM Carrier Frequency).
Note: When operating in the Vector Control mode, the carrier frequency should be set to
2.2 kHz or above.
Motor/Load Combinations
When the ASD is used in combination with one of the following motors or loads, it may result in unstable
operation.
• A motor with a rated capacity that exceeds the motor capacity recommended for the ASD.
• An explosion-proof motor.
When using the ASD with an explosion-proof motor or other special motor types, lower the carrier
frequency to stabilize the operation. DO NOT set the carrier frequency below 2.2 kHz if operating the
system in the vector control mode.
Note: When operating in the Vector Control mode, the carrier frequency should be set to
2.2 kHz or above.
If the motor being used is coupled to a load that has a large backlash or if coupled to a reciprocating load,
use one of the following procedures to stabilize motor operation.
• Adjust the S-pattern acceleration/deceleration setting,
• If operating in the Vector control mode, adjust the response time, or
• Switch to the Constant Torque control mode.

Load-Produced Negative Torque
When the ASD is used with a load that produces negative torque (an overhauling load), the over-voltage
or over-current protective functions of the ASD may cause nuisance tripping.
To minimize the undesirable effects of negative torque, the dynamic braking system may be used. The
dynamic braking system converts the regenerated energy into heat that is dissipated using a braking
resistor. The braking resistor must be suitably matched to the load. Dynamic braking is very effective in
reducing the DC bus voltage during a momentary over-voltage condition.
If under extreme conditions the dynamic braking system or a component of this system were to fail, the
dynamic braking resistor may experience an extended over-current condition. The DBR circuit was
designed to dissipate excessive amounts of heat and if the extended over-current condition were allowed
to exceed the circuit parameters, this condition could result in a fire hazard.
To combat this condition, the 3-phase input may be connected using contactors that are configured to open
in the event of an extended DBR over-current condition or an internal circuit failure. Using a thermal
sensor and/or overload protection as the 3-phase input contactor drive signal, the contactors will open and
remove the 3-phase input power in the event of an extended DBR over-current or system over-voltage
condition. See Dynamic Braking Protection on pg. 283 for more information on using dynamic braking
with the P9 ASD.
Motor Braking
The motor may continue to rotate and coast to a stop after being shut off due to the inertia of the load. If an
immediate stop is required, a braking system should be used. The two most common types of motor
braking systems used with the ASD are DC Injection Braking and Dynamic Braking.
For further information on braking systems, see DC Injection Braking on pg. 129 and Dynamic Braking
on pg. 141.
