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

  • The natural frequency of a speed setpoint filter is greater than the Shannon sampling frequency from the sampling theorem

Troubleshooting Steps

  1. 1The natural frequency in Hz of a speed setpoint filter must be less than the reciprocal value of two speed controller cycles.
  2. 2Speed filter: MD 5520 * 0.01 * MD 5514 < 1 / ( 2 * MD 5001 * 31.25 microsec) - BSP natural frequency drive MD 5520: SPEED_FILTER_1_BS_FREQ - BSP blocking frequency drive MD 5514: SPEED_FILTER_1_SUPPR_FREQ - Speed controller cycle drive MD 5001: SPEEDCTRL_CYCLE_TIME
  3. 3Clear alarm with the RESET key in all channels. Restart part program. 2-791
