1) Each channel has a separate overvoltage monitor for the power supply at the input. If the voltage at the
input exceeds the permissible maximum value, the channel is shut down.
2) High test pulses must never occur simultaneously at inputs #STO-A and #STO-B, but only with a time
offset.

14.4 Characteristic curves
Required power reduction
Mounting clearances may be required at output currents > 4.6 A to ensure the
device reaches its specified service life. The required mounting clearances depend
on the ambient temperature and the output current.
Mounting clearances from 0 mm are possible for a device compound consisting
of several servo drives CMMT-ST. The following characteristic curves show the
maximum permissible effective currents for the lateral mounting clearances 0 mm,
3 mm, 10 mm and 15 mm.

– Use 60/75 °C copper conductors only:
– [X6], motor connection
– [X9], load and logic voltage
– Use in an environment with pollution degree 2 (or better).
– Maximum surrounding air temperature: 50 °C
– With correct parameterisation of the nominal motor current, the motor is pro-
tected against overloading by the I²t monitoring function.
– For the load voltage supply, the use of a suitable fuse is recommended in
accordance with the following table.
