Note:
As standard, the drive contains capacitors connected between the main circuit and
the frame. These capacitors and long motor cables increase the ground leakage current
and may cause nuisance faults in residual current devices.
Implementing the emergency stop function
For safety reasons, install the emergency stop devices at each operator control station and
at other operating stations where emergency stop may be needed. Implement the emergency
stop according to relevant standards.
Note:
You can use the Safe torque off function of the drive to implement the Emergency
stop function.
Implementing the Safe torque off function
See
The Safe torque off function (page 171)
.
Implementing the undervoltage control (power-loss
ride-through)
Implement the power-loss ride-through function as follows:
•
Check that the power-loss ride-through function of the drive is enabled with parameter
30.31 Undervoltage control
.
•
Set parameter
21.01 Vector start mode
to Automatic (in vector mode) or parameter
21.19 Scalar start mode
to Automatic (in scalar mode) to make flying start (starting into
a rotating motor) possible. If the installation is equipped with a main contactor, prevent
its tripping at the input power break. For example, use a time delay relay (hold) in the
contactor control circuit.
WARNING!
Make sure that the flying restart of the motor will not cause any danger. If you are
in doubt, do not implement the Power-loss ride-through function.
Using power factor compensation capacitors with the drive
Power factor compensation is not needed with AC drives. However, if a drive is to be
connected in a system with compensation capacitors installed, note the following restrictions.
WARNING!
Do not connect power factor compensation capacitors or harmonic filters to the
motor cables (between the drive and the motor). They are not meant to be used
with AC drives and can cause permanent damage to the drive or themselves.
If there are power factor compensation capacitors in parallel with the input of the drive:
