Parameters: %1 = NC axis number
%2 = Drive number
Definitions: On FDD:
The control is disabled, the motor is decelerated, SIMODRIVE_READY and
DRIVE_READY are canceled.
On MSD:
Pulse delete, motor coasts, SIMODRIVE_READY and DRIVE_READY are canceled.
Note: The reaction (FDD, MSD) can be configured via 611D-MD 1613.0.
Request: During boot-up of the control and cyclically.
With active Safety Integrated (MD 1301 <> 0: $MD_SAFE_FUNCTION_ENABLE (safe
functions enable)), the measuring circuit monitoring of the motor (incremental) must be
activated via MD 1600: $MD_ALARM_MASK_POWER_ON (concealable alarms (Power
On) bit 4.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.

- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Activate measuring circuit
monitoring of motor (incremental).
Program Con-
tinuation:
Switch control OFF - ON.
300777 Axis %1 drive %2 rotor position identification current too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The current set in MD1019: $MD_CURRENT_ROTORPOS_IDENT (current rotor position
identification) is greater than the permissible current for the motor and the power section
used.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - NC not ready.
- The NC switches to follow-up mode.

- 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. Reduce MD1019:
$MD_CURRENT_ROTORPOS_IDENT (current rotor position identification).
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
