Planning the electrical installation
64
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.
Note:
Pressing the stop key (
) on the control panel of the drive does not generate
an emergency stop of the motor or separate the drive from dangerous potential.
Implementing the Safe torque off function
The drive includes the Safe torque off function. For more information, see
Safe
torque off function for ACSM1, ACS850 and ACQ810 drives application guide
(3AFE68929814 [English]).
Implementing the ATEX-certified Safe motor disconnection function
(Q971)
With Q971, the drive provides ATEX-certified safe motor disconnection
without contactor using the drive Safe torque off function. For more information, see
ATEX-certified Safe disconnection function for ACS850 drives (+Q971) application
guide
(3AUA0000074343 [English]).
Implementing the Power loss ride-through function
Implement the power loss ride-through function as follows:
1. Activate the power loss ride-through function of the drive (parameter
47.02 Undervolt ctrl
in the Standard Control Program).
2. 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.
