Error value clearing function: when the following conditions occur, PCI-M324 outputs an ERC
signal to the servo drive.
(1) PEL and MEL signals are triggered.
(2) EMG hardware circuit is triggered.
(3) Software EMG stop signal is triggered (API: _m324_emg_stop_erc).
(4) Force output ERC signal is triggered (API: _m324_set_erc_on).

servo drive before starting the servo drive.
