Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
When selecting the rotor position identification (MD1011 bit 12 or bit 13) only converter frequencies (MD1100) of 4 kHz/8 kHz are permissible.
• Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration IM)
• Modify MD 1100: $MD_PWM_FREQUENZY (pulse width modulation frequency) The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
