From version 1.18

The upper bits in Reg. 35 ( ERR_STAT ) have now been applied to this register and is:

  • Bit 18: Not used.

  • Bit 19: VAC_ON. This bit indicates that 230 VAC inlet is

switched on. You may try to switch power on / off and watch the status

of bit 19.

The bit is used internally in agreement with the

undervoltage setup.

  • Bit 20: PWM_LOCKED. This bit indicates that a severe error has

occurred, and that any activity on the outlet to the motor

windings has been stopped to protect the drive. This bit

can only be reset by switching 24 VDC power off / on.
