Fig. 5-26: Activating an external holding brake
● The maximum current that can be used to activate the exter‐
nal holding brake is 24 V DC 1.2 A. We recommend that you
activate 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
avoided by setting the PLC axis interface signal

The descent of a vertical axis may result in
fatal injuries!
● The maximum holding torque that can be applied by the optional holding
brake of the MSK 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
Digital input and output signals
In the basic device, the MTX micro features 32 digital inputs (24 V DC) and
16 digital outputs (24 V DC, 500 mA). The number of I/Os can be extended to
a maximum of 96 inputs and 48 outputs by means of 2 optional modules
DEA40.1 (with 32 I/16 O each). A defined address is assigned to each digital
output in the system PLC program.
