PRECAUTIONS
1) Only turn ON the input power supply after replacing the front cover. Do not remove the cover
while the inverter is powered up.
2) When the retry function (parameter L5-02) is selected, do not approach the inverter or the load,
since it may restart suddenly after being stopped.
3) Since the Stop key can be disabled by a function setting, install a separate emergency stop switch.
4) Do not touch the heatsink or braking resistor, due to very high temperatures.
5) Since it is very easy to change operation speed from low to high speed, verify the safe working
range of the motor and machine before operation.
6) Install a separate holding brake, if necessary.
7) Do not check signals during operation.
8) All inverter parameters have been preset at the factory. Do not change the settings unless required.
Failure to observe these precautions may result in equipment damage, serious personal injury or death.

VS-616G5 Programming Manual 5
Introduction
Introduction
Thank you for purchasing Yaskawa’s VS-616G5 high performance vector inverter. The G5 employs
the latest hardware and software technology to provide unmatched performance, reliability and appli-
cation flexibility.
The G5 flexible control mode architecture allows four choices of motor control technology for your
application:
·Open Loop Vector is best for most applications, as it offers Adaptive Vector Control technology
(AVC™) for precise speed regulation, quick response and high starting torque.
·Closed Loop Flux Vector is the choice for applications requiring torque control, very precise speed
regulation and full torque control at zero speed.
·V/f (Volts per Hertz) mode with Yaskawa’s proprietary full range auto-torque boost provides ideal
control for multi-motor applications.
·Closed Loop V/f allows encoder feedback for use with the Volts/hertz mode.
Use the following key to determine which control mode and access level are available for each parameter.
Q: Quick-Start Level, selected parameters for maintenance-level programming
B: Basic Level, selected parameters for basic programming in most applications
A: Advanced Level, all parameters for advanced programming in special applications
The menu structure for all access levels are the same for the Operation, Initialize, Auto-tuning and
Modified constants sections. The Programming section menu structure for each access level is as fol-

time set in deceleration time 1 (C1-02) and DC injection braking is applied after the minimum output
frequency (E1-09) has been reached. If the deceleration time is set too short or the load inertia is large,
an overvoltage fault (OV) may occur during deceleration. In this case, increase the deceleration time or
install an optional braking transistor and/or braking resistor (braking transistors are provided as stan-
dard for units 230V 7.5kW and smaller, 460V 15kW and smaller).
Braking torque: without braking resistor, approx. 20% of motor rated torque
with braking option, approx. 150% of motor rated torque

·Coast to Stop (B1-03 = “1”)
Upon removal of the FWD (REV) run command, the motor starts to coast. After a stop command is
given, a run command is accepted and operation will start after the minimum baseblock time (L2-03)
elapses. If there is a possibility that a run command might be entered before the motor has come to a
stop, the speed search function (B3) or Coast to Stop with Timer 1 (B1-03 = “3”) should be employed.
·DC Injection Braking to Stop (B1-03 = “2”)
Upon removal of the FWD (REV) run command, the motor brakes to stop, according to the DC injec-
tion braking time at stop set in B2-04. If this value is set to “0” (factory default), DC injection braking
is disabled, and the motor coasts to stop. When choosing this function, note that the actual stop time is
the time set in B2-04 multiplied by 10 (see Figure 3 above). This stopping method is disabled during
flux vector control. Braking duty cycle should allow excess motor heat to dissipate.

·Coast to Stop with Timer 1 (B1-03 = “3 ”)
After a stop command is given, a run command is not accepted while the coast to stop timer elapses
(same as Decel 1). After the timer runs out, another run command must be given for the inverter to
begin acceleration. This stopping method is disabled during flux vector control.
A “reverse run disabled” setting does not allow a reverse run command from the control circuit termi-
nal or the digital operator. This setting is used in applications where a reverse run command is undesir-
able.

DC injection braking at start can be used to stop a spinning motor (or when motor rotation direction is
unknown) prior to running. DC injection braking time at start (or initial excitation for flux vector con-
trol) is set in units of 0.1 second. When B2-03 is set to “0”, DC injection braking is disabled and accel-
eration starts from the minimum output frequency.

DC injection braking time at stop (or initial excitation for flux vector control) is set in units of 0.1 sec-
ond. When B2-04 is set to “0”, DC injection braking is disabled, and the inverter output shuts OFF.
When coast to stop is selected as the stopping method (B1-03), DC injection braking at stop is disabled.
Setting Range: 0 to 500%

This parameter allows the magnetizing motor flux to be boosted when starting the motor. This parameter
will facilitate a quick ramp-up of the torque reference and magnetizing current reference to reduce motor
slip during start. A setting of 100% equals motor no-load current E1-09. This flux level will be applied
below Minimum Output Frequency (E1-09) until the DC Injection Time at Start (B2-03) expires. This
parameter is useful when starting motors that are relatively larger than the inverter, due to the requirement
for increased magnetizing current. This parameter may also compensate for reduced starting torque due to
motor circuit inefficiencies.

B3 Speed Search
When starting into a coasting motor, use the speed search command or DC injection braking at start, to
prevent a drive trip and motor burnout.
This function allows the restart into a coasting motor without the necessity to stop. It is useful during
inverter bypass operation, when switching between the motor receiving power directly from the line
and from the inverter. Two interlocking contactors must be employed for commercial power switcho-
ver to prevent line power from being applied to the inverter output terminals.
Set the multi-function contact input selection (H1-01 to H1-06) to “61” (start search command from
maximum output frequency), “62” (start search command from the set frequency), or “64” (start
search command from the SFS frequency when baseblock is applied).
Note: This parameter is disabled except when (A1-02=1) (V/F w/PG Fdbk) or 3 (Flux Vector)
Setting Range: 0 to 200%
Factory Default: 150%
After power loss and recovery, speed search begins to ramp the frequency down from a specified point in
order to locate the frequency of the spinning motor. During initial speed search the inverter’s output cur-
rent exceeds the speed search detection current level. This level is set as a percentage of inverter rated
current. When the inverter’s output current is less than the speed search detection level, the frequency is
interpreted as the speed agree level, and the inverter accelerates/decelerates to the specified frequency.
Note: Factory setting defaults to 150 when A1-02=0 (V/F Control). When A1-02=2 (Open Loop Vec-
tor), the default is 100.

Sets deceleration time during speed search in units of 0.1 second. When speed search deceleration time
is set to 0.0 second, speed search is disabled. The speed search deceleration time should be set to be
somewhat faster than the decel rate of coasting motor. Build an input sequence so that the speed search
command is input at the same time or prior to the FWD (REV) run command. If the run command is
input before the search command, the search command is not effective. Below is a timing diagram of
the search command input:
B4 Delay Timers
The inverter input and output contacts can be used in place of an external timer. When multi-function
contact input (H1-__ = “18”) is closed, a multi-function contact output (H2-__ = “12”) can be set to
close after the On-delay time (B4-01) has expired. When multi-function contact input (H1-__ = “18”)
is opened, a multi-function contact output (H2-__ = “12”) can be set to open after the Off-delay time
(B4-01) has expired. This function operates independently of any action the inverter is performing.
Setting Range: 0.0 to 100.0s
Factory Default: 0.0s
Sets the ON-delay time in units of 0.1 second. The multi-function input must be “closed” for longer
than the ON-delay timer for the multi-function output to close.

B5 PID Control
The Proportional, Integral and Derivative (PID) control function provides closed-loop control and reg-
ulation of a system variable such as temperature or pressure. A control signal based on the difference
(or proportion) between a feedback signal and a desired setpoint is produced. Integration and deriva-
tive calculations are then performed on this signal, based upon the PID parameter settings (B5-01 to
B5-08), to minimize deviation, for more precise control.
Proportional - P
PID refers to the type of action used to control modulating equipment such as valves or dampers. With
proportional control, a control signal based on the difference between an actual condition and a
desired condition is produced. The difference, such as that between an actual temperature and setpoint
is the “error”. The inverter adjusts its output signal related directly to the error magnitude.
Integral - I
The integral action is designed to minimize offset. An integrating term is used to observe how long the
error condition has existed, summing the error over time. Once the system has stabilized, the offset
would be minimized.
Derivative - D
Overshoot refers to a control loop tendency to overcompensate for an error condition, causing a new
error in the opposite direction. Derivative action provides an anticipatory function that exerts a “brak-
ing” action on the control loop. When combined, the proportional integral, and derivative actions pro-
vide quick response to error, close adherence to the setpoint, and control stability.
