NOTICE
Risk of the resistor overheating if the temperature switch is not connected
If the temperature switch is not connected, this can cause the resistor to overheat.
• Connect the temperature switch.
Terminals X21.3 and X21.4
For operation, the 24 V DC voltage must be connected to terminal X21.3 and ground to
terminal X21.4.
Pulse cancellation is activated if the power supply is disconnected. As a consequence,
regenerative feedback is deactivated and the bypass relay drops out. If the Line Module is
not disconnected from the line supply when the EP terminal is de-energized, for example,
because a line contactor is not installed, then the DC link remains charged.
Danger to life due to electric shock in the event of voltage flashovers at the temperature
sensor
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
• Use temperature sensors that comply with the specifications relating to protective
• If safe electrical separation cannot be guaranteed (for linear motors or third-party
