Activating an External Holding Brake
To secure vertical axes or to connect a spindle brake, an external holding brake
can be connected to each X6 terminal. As is the case with the motor brake, this
brake will also be automatically controlled by the MTX micro-c.
Fig.4-19:
Activating an external holding brake
●
The maximum current that can be used to activate the external
holding brake is 24 V DC 1.2 A. We recommend that you ac‐
tivate the external brake by a relay.
●
The maximum switching frequency of the brake is 0.5 Hz.
●
Switching of the external axis should be diagnosed in the PLC
program. Travel commands with applied brake must be avoi‐
ded by setting the PLC axis interface signal qAx_DrvLock.
DANGER
●
The maximum holding torque that can be applied by the optional holding
brake of the MSK/QSK motors is the nominal motor torque.
●
The motor holding brake alone cannot be used as a holding brake for the
purpose of personal protection.
●
If the holding torque is higher, use must be made of a suitable external
brake.
