DANGER
Dangerous movements! Danger to personnel 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 guar‐
antee the safety of personnel!
Personnel safety must be achieved using higher-ranking, fail-safe procedures:
●
Dangerous areas should be blocked off with protective fences or grids
●
Additionally secure vertical axes against falling or dropping after switching
off the motor power by, for example:
–
mechanically securing the vertical axes
–
providing external braking/catching/clamping mechanisms
–
ensuring sufficient equilibration of the vertical axes
Function
The 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 24V supply (connection X13 at HCS02
power sections) to the output for controlling the motor holding brake.
The integrated 24V control voltage supply of power sections of the
order code ‑NxxV is not available at the connection point X6 (see
figure below “Block diagram of internal control voltage”). Therefore,
an external 24V supply is required for controlling the motor holding
brake.

Notes on Installation
Make sure the voltage supply for the motor holding at the motor
brake is sufficient. You have to take into account that voltage drops
on the supply line. Use connecting lines with the highest possible
cross section of the single strands.
