To supply auxiliary equipment (e.g. separately-driven fan for motor),
the drive must be properly connected to terminals (L1) to (L3). The
supply voltage of the auxiliary equipment must match the input volt‐
age. The voltage is supplied at terminals X ... Depending on which
option (option N30 to N33) is chosen, different circuit-breakers are
available with the assigned motor circuit-breaker. When connecting
the power supply, take into account the direction of rotation of the
drive. Set the motor circuit-breaker so that it protects the drive. Protect
the auxiliary supply for the auxiliary equipment (e.g. separately-driven
motor fan) with fuses on the system side. The circuit-breaker is acti‐
vated by means of the "Auxiliary equipment ON" command from the
drive controller.
Operating the drive from a higher-level control system / control room.
Connect the control lines as specified in the interface assignment.
Connect the shield. Route the digital and analog signals with separate
cables to minimize interference. Ensure that the required distance
from the power cables is maintained.
Set selector switches S5.0 / S5.1 appropriately when the analog in‐
puts on the customer terminal strip are used as current or voltage
inputs.
To supply the anti-condensation heating for the motor or the working
machine, the drive must be properly connected to terminals (L1) to
(L3).
The supply voltage of the anti-condensation heating must match the
input voltage. The voltage is supplied at terminals X ... Depending on
which option (option N35 to N38) is chosen, different circuit-breakers
are available with the assigned motor circuit-breaker. Set the motor
circuit-breaker so that it protects the anti-condensation heating. Pro‐
tect the auxiliary supply for the anti-condensation heating with fuses
on the system side. The circuit-breaker is activated by means of the
"Auxiliary equipment OFF" command from the drive controller.
Option L60
The drive is fitted as standard with a category 0 STOP function and an
EMERGENCY OFF button in the control cabinet door. With option
L60, EMERGENCY OFF category 1 (decelerate at current limit) is
defaulted. If the drive is to be integrated in a central EMERGENCY
STOP sequence in the system-side protection concept, floating con‐
tacts are available on terminal strip X...
Terminal X... allows other EMERGENCY OFF buttons in the system
to be looped in.
Signal connections
Operating the drive from a higher-level control system / control room.
Connect the control cables in accordance with the interface assign‐
ment and apply the shield. Route the digital and analog signals with
separate cables to minimize interference. Ensure that the required
distance from the power cables is maintained.
Note that when the analog inputs on the customer terminal strip are
used as current or voltage inputs, the isolation amplifiers ( ... ) must be
set accordingly.
