These parameters are used in Sensorless applications [4]. Refer to DMC for details.
M6-14 Maximum radius voltage “Vmodmax”
From SW release V02.08.05 it is possible to deliver full PWM voltage output to motor for achieving maximum possible
voltage from the battery. This is possible by increasing the value of this setting. If set to 102% full PWM wave will be
provided at high speed.
To take advantage of this there are two chances:
1) Set “Vmodmax” to 102% before doing autotuning.
2) Set “Vmodmax” to 102% and do recalculation.
Suggested option is number 1)
If after increasing the “Vmodmax” the motor behavior becomes unstable at high speed bring back “Vmodmax” to 95%
and perform recalculation.
