SINUMERIK 840D/840Di/810D Diagnostics Guide (DA), 10.04 Edition
Axis %1 drive %2 generator mode: converter frequency rotor position identification
%1 = NC axis number
%2 = Drive number
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_FREQUENCY (pulse width modulation frequency)
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Please inform the authorized personnel/service department.
Change the converter frequency (MD 1100) or deselect rotor position identification
(MD1011 bit 12 or bit 13).
• Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration
IM)
• Modify MD 1100: $MD_PWM_FREQUENCY (pulse width modulation frequency)
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 motor moment of inertia less than or equal to zero
%1 = NC axis number
%2 = Drive number
The value in MD 1117: $MD_MOTOR_INERTIA (motor moment of inertia) is less than or
equal to zero.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Please inform the authorized personnel/service department.
• For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
• For MSD, configure "1st motor" first.
• For third-party motors: Enter a valid value in drive MD 1117: $MD_MOTOR_INERTIA
(motor moment of inertia).
Clear alarm with the RESET key in all channels. Restart part program.
