How to set the "inverter motor brake" function for an oscillation-reduced operation:
For V/f characteristic open-loop control/closed-loop control (VFCplus):
• Set additive speed ( C00987 ) to rated slip speed.
• Adapt the deceleration ramp so that the deceleration time is slightly below (10 ... 30 %)
the deceleration time that can be realised with the inverter motor brake.

How to set the "inverter motor brake" function for a maximum acceleration ramp:
For V/f characteristic open-loop control/closed-loop control (VFCplus):
• Set additive speed ( C00987 ) to 1,5 ... 2,5-fold rated slip speed.
• Adapt the deceleration ramp so that the deceleration time is slightly below (10 ... 30 %)
the deceleration time that can be realised with the inverter motor brake.
For sensorless vector control (SLVC):
• Set additive speed ( C00987 ) to 2 ... 4-fold rated slip speed.
• Adapt the deceleration ramp so that the deceleration time is slightly below (10 ... 30 %)
the deceleration time that can be realised with the inverter motor brake.
