MyLink Axis Module Screen Explanation - Module Settings Area
4.Interface I/O: There are two main functions used for configuration:
- Related I/O logic for servo/stepper drives, such as ALM/INP/ERC
– Special signals for servo motors: INP and ERC
– INP: Signal generated when the servo motor completes the tuning state
– ERC:Signal used by the servo motor for an emergency stop action. Output by the control card
– A digital input point on the servo drive (clearance signal for the deviation counter of the servo drive)
– Function: When the servo drive receives this signal, it immediately clears the deviation counter value within the drive, making it 0. This causes the servo motor to stop immediately
– Mainly used in scenarios like:
– Completion of homing (zeroing)
– Activation of left and right limits
– When the ALM signal is established
– When the EMG signal is established
– General axis control DI logic settings, such as SD/LTC
– SD:Sensor used in the mechanism, mainly for detecting physical touches and reducing speed
– LTC:Sensor used in the mechanism, mainly for detecting physical touches and capturing the current position of the axis
- ALM_Logic: Signal output when there is an error in the servo motor/stepper motor
– Set according to the actual logic of the driver
– Can be configured as Low_Active or High_Active
- ALM_mode:
– Choose the stop mode of the axis when the ALM signal is generated
– EmgStop / SdStop
- INP_Logic: A unique signal for servo motors; generated when the servo motor completes tuning (In Position)
– LowActive/HighActive: When the motor stops, this signal is in the On state
– Mainly used to determine the second condition signal for Motion down
- INP_Enable: Choose whether to enable the INP signal
– Off / On
– Mainly affects the timing of determining Motion Done for the operating axis
– When INP is turned off, Motion Done is generated when the axis module completes pulse output
– When INP is enabled, the timing of Motion Done is as follows: 1. The axis module completes pulse output → 2. Wait for the servo motor to complete tuning, then output the INP signal
- ERC_Logic: Unique signal for servo motors
– LowActive / HighActive
– Mainly used to expedite the stopping of the servo motor
- ERC_On_Time:
– Select the On Time Width
- ERC_Off_Time
– Select the Off Time Width
- SD_Enable:
– On / Off
– Mainly used to select whether to use this signal
- SD_Logic: Set signal logic
– Low Active / High Active
- SD_Mode: Set the operating mode when the signal is generated
– DecOnly: Only decelerate to St_Vel and continue running
– DecStop: Decelerate and stop after reaching St_Vel
- SD_LTC:
– On / Off
– Mainly used to choose whether to enable this signal function
- LTC_Logic: 設定訊號邏輯
– Low Active / High Active
– Position Lock Function: Dynamic capture of the current position
