Alarm 300776

Siemens 300776 - Axis drive measuring circuit monitoring must be active

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 Control reaction: 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.

Safety

  • Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.

Common Causes

  • 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.

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2Activate measuring circuit monitoring of motor (incremental).
  3. 3Switch control OFF - ON
