The use and integration of the ERC signal with MNET single-axis slaves are explained as follows
What does ERC mean?
- A DI point on the servo drive end (clearance signal of the servo drive’s deviation counter)
- Function: When the servo drive receives this signal, it immediately clears the deviation counter value inside the drive, setting it to 0. This causes the servo motor to stop immediately
Operating mode
- The control card (device) outputs a digital output (DO) to the servo drive’s ERC (DI) signal from the master control end
Primary Usage Scenarios
- Completed homing operation
- During positive or negative limit switch actuation
- When ALM signal is activated
- When EMG signal is activated

1._mnet_m1a_set_auto_erc(RingNo, SlaveIP, Enable)
2._mnet_m1a_set_erc_on(RingNo, SlaveIP, on_off)
3._mnet_m1a_set_home_config (RingNo, SlaveIP, home_mode, org_logic, ez_logic, ez_count, erc_out)
Explanation of Command Parameters:
1._mnet_m1a_set_auto_erc
Enable Setting
- 0 : The ERC signal is not output at the stop by inputting EL, ALM, EMG signals, and origin return completed.
- 1 : The ERC signal is automatically output at the stop by inputting EL, ALM and EMG signal, and origin return completed.
2._mnet_m1a_set_home_config
erc_out Setting
- 0 : The ERC signal is not output at completing origin return.
- 1 : The ERC signal is output automatically at completing origin return.

Note: In the _mnet_m1a_set_home_config, make sure to set the ERC out parameter before applying it, ensuring it is not affected by the set auto ERC configuration
