Holding brake
FKM servomotors offer an optional holding brake that applies friction on to
the shaft.
Its purpose is to immobilize or lock vertical axes, not to brake a moving axis.
Its main characteristics depending on the type of brake are:
IMPORTANT. Before installing a servomotor with a holding brake on
the machine, carefully read all the warnings referring to the servomotor
holding brake detailed in section
3 Storage and 5 Installation in the
chapter on GENERAL PRECAUTIONS of this manual.
WARNING.
NEVER use this holding brake to stop a moving axis.
MANDATORY.
The supply of the holding brake shall fulfill requirements of low voltage
limited energy secondary circuits DVC A according IEC/UL 61800-5-1.
INFORMATION.
The FKM96 motor model does not offer the holding brake option.

Note. The max. turning speed of the extra-torque holding brake is 10000 rev/min.
MANDATORY.
A. Never use the holding brake to stop a moving axis.
B. Never exceed its maximum turning speed.
C. Never apply a voltage higher than top Vdc value given in the table that
would prevent the shaft from turning. Remember that the axis is released
when applying a voltage within the range given in the table for the rated
unlocking voltage.
D. When installing the servomotor, make sure that the holding brake fully
releases the shaft before making it turn for the first time.
