Planning the electrical installation
39
a calculated temperature value (based on a motor thermal model) or an actual
temperature indication given by motor temperature sensors. The user can tune the
thermal model further by feeding in additional motor and load data.
The ACSM1-04 has a dedicated connection for PTC or KTY84 sensors. See page
in this manual, and the appropriate
Firmware Manual
for the parameter settings
concerning motor thermal protection.
Ground fault protection
The drive is equipped with an internal ground fault protective function to protect the
unit against ground faults in the motor and the motor cable. This is not a personal
safety or a fire protection feature. The ground fault protective function can be
disabled with a parameter, refer to the appropriate
Firmware Manual
.
The optional mains filter includes capacitors connected between the main circuit and
the frame. These capacitors and long motor cables increase the ground leakage
current and may cause fault current circuit breakers to function.
Emergency stop devices
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.
