This equipment can endanger life through rotating machinery and high voltages.
The equipment contains high value capacitors which take time to discharge after
removal of the mains supply. Before working on the equipment ensure isolation
of the mains supply from terminals L1, L2/N and L3 (as applicable). Wait for at
least 3 minutes for the capacitors to discharge to safe voltage levels (<50 V)
Failure to do so constitutes AN ELECTRICAL SHOCK HAZARD.
When replacing a drive in an application, and before returning to use, it is
essential that all user defined parameters for the product's operation are
correctly installed.
Failure to do so may create A HAZARD AND RISK OF INJURY.
WARNING! The metal parts may reach 90°

The 601 range of Frequency Inverters is designed for speed control of standard 3-
phase induction motors. The range covers motor power ratings from 0.37kW (1/2hp)
to 2.2kW (3 hp).
The 601 features built in programming/operator controls and (optional) EMC
compliant RFI filters. A pullout instruction guide provides quick reference for LED
codes and terminal description.
Suitable members of the 601 range can operate from either a single phase two wire
supply of 220/240 Volts or 3 wire 380 - 460 Volts supply, 50/60Hz.
The 400V 3-phase 601 range has an internal dynamic brake switch, this allows the
user easy and convenient connection to an external resistor.
Advanced microprocessor technology provides a pulse width modulation strategy for
quiet operation.
The 601 control terminals are SELV, i.e. double insulated from power circuits to
allow easy and safe system interconnection.
The 601 is protected against overloads, excessive voltages and both phase to phase
and phase to earth short circuits via an intelligent monitoring strategy. This avoids
nuisance tripping and gives trouble free operation.
Optional internal RFI filters offer full electromagnetic compatibility (EMC) for the
majority of applications without the need for additional external components. A
comprehensive guide to EMC compliance is given in Chapter 6.

Three seven segment LED displays provide drive programming, status and
diagnostic values. Refer to the following tables for further information:
• Table 5.1 for User Adjustable Parameters description (pages 5-1 and 5-2).
• Table 5.2 for Drive Status description (page 5-5).
• Table 5.3 for Diagnostics information (page 5-6).

The Function Keys are used to navigate around the Man Machine Interface (MMI)
structure as well as control the drive if LOCAL MODE is selected (See Chapter 5).

This key is used to scroll through the TITLE LEVEL or increase parameter
values.
This function key is also used to increase the local setpoint and thus the
inverter frequency when LOCAL mode is selected
DOWN
This key is used to scroll through the TITLE LEVEL or to decrease parameter
values. This function key is also used to decrease the local setpoint and thus
the inverter frequency when LOCAL mode is selected.

This panel gives the user sufficient information for basic operation of the product:
• Translates the drive status information given in mnemonic form on the LED
display (eg RDY = Ready; OC = Overcurrent).
• Decodes the titles of the parameters (P1 to P15) and the diagnostics (D1 to D3)
shown on the LED display (eg D1 = Frequency).
• Where parameters are used to select an operating mode it decodes the numbers
assigned to each mode (eg P11 mode 1 = Coast to Stop).
• Shows the function of each control terminal.

where necessary to comply with local wall mount requirements. To maintain
compliance with the European Electrical Safety Standard VDE0160(1994) /

In normal operation the 601 dissipates heat and must therefore be mounted to allow
the free flow of air vertically through the ventilation slots and heatsink. Care must be
taken to ensure that the mounting surface is cool and that heat generated by other
adjacent equipment is not transmitted to the 601. Provided the minimum clearance
for ventilation is adhered to these products maybe mounted side-by-side.

Control wiring should be segregated from all power wiring. To comply with the
radiated emissions requirements of EN50081-1 the product must be inside a suitable
control cubicle and the control cables must be screened outside of the cubicle.
Connect the screen to earth at the 601 end only (see figure 4.3). Note the cubicle
must provide 15dB attenuation to radiated emissions between 30 and 100MHz to
meet the residential limits.
0RWRU#:LULQJ
To meet the generic EMC Standards and minimise the electrical interference,
connections between the Inverter and the motor must be made using screened cable.
The screens must be connected to the motor frame and to the motor cable clamp
(PE). The motor protective earth conductor should be connected at the drive end to
the motor PE point. Where it is necessary to interrupt the screened cable for
connection to circuit breakers or other devices, the screens should be connected over
the shortest distance possible.
The motor cables should be segregated from all other wiring and should not be run in
the same conduit/trunking as supply or control wiring. The recommended method for
terminating the screen on screened motor cables is shown on the following figure.

Remove terminal cover (figure 1.1). For typical power connections refer to figure 4.3.
Eurotherm Drives do not recommend the use of RCDs. If local regulations dictate
their use, RCDs which function with DC components of earth leakage current (Type
B as defined in IEC 755/A2) RCDs are only acceptable, otherwise all loads requiring
protection with the RCD will be at risk. Filtered 601s must be permanently earthed

by using two independent protective earth incoming supply conductors (figure 4.3).
This is due to the high earth leakage current when using filters.
The incoming mains supply should be protected by a suitable fuse or circuit breaker,
as shown in table 2.1.
Power cables should be
specified to this table:-
7DEOH#714
When the wires are fully inserted into the terminal to maintain IP20 protection they
need to be stripped to 5 - 6 mm (0.22 in).
&RQWURO#:LULQJ
All control and signal terminals are SELV, i.e., protected by double/reinforced
insulation. Ensure all wiring rated for highest system voltage. Control wiring of
between 0.08 mm2(28 AWG) - 2.5 mm2(14 AWG) can be used.
Remove the terminal cover (see figure 1.1). Rotate the Control Cable Retainer, route
the control cables in the right hand compartment and wire to the control terminals.
Rotate the Control Cable Retainer to hold the cables in the designated compartment.
Figure 4.4 shows a typical control connections required for operation as a simple
speed controller.
* It is recommended that the
“0V/common” be connected to
protective earth/ground for safety
reasons. In a system comprising
of more than one controller, the
“0V/common” signals should be
connected together and joined to
protective earth/ground at one
point only. This is mandatory to
meet the EMC specification
stated.

During deceleration, or with an overhauling load, the motor acts as a generator.
Energy flows back from the motor into the DC link capacitors within the Frequency
Inverter. This causes the DC link voltage to rise. If the DC link voltage exceeds
810V then the Frequency Inverter will trip to protect the capacitors and the Inverter
power devices. The amount of energy that can be absorbed in the capacitors is
relatively small; typically more than 20 % braking torque will cause the Frequency
Inverter to trip on overvoltage. Dynamic braking increases the braking capability of
the Frequency Inverter by dissipating the excess energy in a high power resistor
connected across the DC link. See Figure 4.5 for Dynamic Brake Switch
specification.
When the DC link voltage rises
above 750 V, the brake unit switches
the external resistor network across
the DC link. The brake unit switches
off again when the DC link voltage
falls below the threshold level. The
amount of energy produced by the
motor during regeneration depends
upon the RAMP DOWN TIME
parameter and the inertia of the load.
