4.2 Electrical connection
4.2.1 Notes on the electrical connection
NOTICE!
Electrostatic discharges to the MCS connections can damage the electronic components
 Observe the ESD protective measures.
 Carry out work only at ESD-protected workstations.
 Connect the connections as per the pin assignment (see chap. 4.2.3.1, p. 19)
NOTICE!
Risk of damage caused by back-induced voltage.
If the motor shaft is driven externally, the motor acts as a generator. The generated voltage
can damage the electronics of the IMC. The generated DC voltage (U
mot
) corresponds to the
product of speed (n) and electromotive force constant (k
n
).

Connect the electronics supply of the MCS to a power supply unit during installation or
connect the U
mot
and GND connections to each other.
 Do not drive the MCS above the specified maximum and nominal speed, even if a gear -
head is used.
 Use an EMC suppressor circuit (see chap. 4.3, p. 26).
NOTICE!
Extreme static or dynamic loads on the connection cable can cause the cable to be dam -
aged.

Make sure that the connection cable is not subjected to abrasion, crushing or exces -
sively tight bending radii during installation and operation.

Do not bend the cable at temperatures < –10 °C.

Comply with permissible loads (see Tab. 3).
