X6, Motor Temperature Monitoring and Motor Holding Brake
Dangerous movements! Danger to persons
from falling or dropping axes!
The standard motor holding brake provided or an external motor holding
brake controlled directly by the drive controller are not sufficient on their own
to guarantee personal safety!
Personal safety must be achieved using higher-level, fail-safe measures:
● Block off danger zones with safety fences or safety guards
● Additionally secure vertical axes against falling or dropping after switch‐
ing off the motor power by, for example,
– mechanically securing the vertical axes
– adding external braking/arrester/clamping mechanisms
– ensuring sufficient equilibration of the vertical axes
Lethal electric shock by live parts with more
than 50 V!
The input of the motor temperature evaluation is not galvanically isolated
from the housing. If the voltage applied to the input is impermissibly high (e.g.
because of a flashover of the motor winding voltage), this voltage may come
into contact with the housing. Ensure that the temperature sensor of the con‐
nected motor has a double isolation against the motor winding.
Excessive voltage at the input of the motor
temperature evaluation may cause damage
to the device!
The voltage allowed at the input of the motor temperature evaluation must
correspond to the allowed control voltage of the device. If the voltage applied
to the input is impermissibly high, the device may be damaged.
Function
Connection point X6 contains the connections for
● monitoring the motor temperature
● controlling the motor holding brake
Via an integrated contact element (BR), the power section
switches the voltage of the external 24-V supply to the output for
controlling the motor holding brake.
