point smoothing) is greater than or equal to the value in MD 1245:
$MD_CURRENT_SMOOTH_HYSTERESIS (threshold of the speed-dependent M set-
point smoothing).
Reactions: - 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.
Remedy: Please inform the authorized personnel/service department. Check and, if necessary, cor-
rect the torque adaptation factor MD 1246: $MD_CURRENT_SMOOTH_HYSTERESIS
(hsyterisis of the speed-dependent M setpoint smoothing) or MD 1245:
$MD_CURRENT_SMOOTH_HYSTERESIS (threshold of the speed-dependent M set-
point smoothing). $MD_CURRENT_SMOOTH_SPEED.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.

Axis %1 drive %2 adaption factor of torque limit invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The torque adaptation factor MD 1191: $MD_TORQUE_LIMIT_ADAPT_SERVO (adapta-
tion of servo limit torque) exceeds the format limit.
Reactions: - 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.
Remedy: Please inform the authorized personnel/service department.
• For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
• For third-party motors: Check and, if necessary, correct the torque adaptation factor MD
1191: $MD_TORQUE_LIMIT_ADAPT_SERVO (adaptation of servo limit torque).
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:

Axis %1 drive %2 generator mode: response voltage > switch-off threshold
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The sum of the values in MD1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage
for generator axis) + MD1632: $MD_LINK_VOLTAGE_GEN_HYST (voltage range for
generator control) is greater than MD1633: $MD_LINK_VOLTAGE_GEN_OFF (deactiva-
tion threshold for generator axis).
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
