The profile generator c alculates the speed profile from the set profile parameters.
l
The parameters can be changed during homing.
– C0935 and C0936 become effective if REFC-ON = LOW.
l
The drive should not run at the torque limit (MCTRL-MMAX = HIGH)otherwise the drive might
not be able to follow the speed profile.
– Prolong acceleration / deceleration time C0936 until MCTRL-MMAX does not respond any
more.
l
The phase controller in FB MCTRL must be activated.
