Current limiting
The current limiting additionally limits the maximum torque which the motor can
provide. If the torque limit is increased, more torque is only available if a higher
current can flow. It may be necessary to also adapt the current limit. The current
limiting is influenced by:
¾
P0640 motor overload factor
¾ Thermal motor protection (refer to Section 3.21)
¾ Thermal drive inverter protection (refer to Section 3.22)
After limiting, the instantaneous maximum possible drive inverter current is
displayed in parameter r0067 (limited output current).
