NOTICE
Voltage peaks during braking operation
During braking of high inertial masses and/or when using short braking times the
DC main voltage can increase significantly depending on the parameterized supply
voltage.
▶ supply voltage 24 V
DC
→ max. overvoltage 40 V
DC
▶ supply voltage 48 V
DC
→ max. overvoltage 70 V
DC
▶ supply voltage 80 V
DC
→ max. overvoltage 110 V
DC
The connected power supply unit must be designed for this voltage. If not, you
need to decouple the main voltage by means of a blocking diode to avoid damage
to the power supply unit (see connection example
page 48).
