Motor Modules

6.2 Safety information

Characteristics of the Motor Modules
● Version for 510 ... 720 V DC (line voltage 380 ... 480 V 3 AC) from 210 to 1405 A
Version for 675 ... 1035 V DC (line voltage 500 ... 690 V 3 AC) from 100 to 1560 A
● Liquid cooling
● Short-circuit/ground-fault-proof
● Electronic rating plate
● Operating status and error status via LEDs
● DRIVE-CLiQ interface for communication with the Control Unit and/or other components
in the drive line-up.
● Integration in system diagnostics
● An external 24 V DC power supply is required to operate liquid-cooled Motor Modules.
The volumetric flow of the coolant is monitored by the software. If the volumetric flow is
continuously lower than the setpoint, an alarm (A5005) is first displayed. If this alarm
remains active continually for the next 5 minutes, a fault message (F30047) is activated
which shuts down the unit.
The fans for the internal electronic circuitry are only switched on when required.
The fans are switched on and off as a function of several factors (e.g. heat sink temperature,
ambient temperature, output current, duty cycle, ...) which means that fan operating cycles
cannot be calculated directly.
6.2 Safety information
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
