Function Overview

The core functions of the module revolve around the position control, speed control, and mode switching of the motor, supporting various flexible operations, as follows:

Function Name Core Description Operation Points

The positioning operation is performed according to the instructions of the CPU module. After setting the target position, speed, acceleration and deceleration parameters, the "start operation instruction" relay is triggered. After the positioning is completed, the "positioning end" relay can be set to absolute/relative position; The acceleration and deceleration curves can be trapezoidal, two-stage, or S-shaped; Can set the positioning judgment range and timeout period; Support normal startup or waiting for internal/external trigger startup

Target position change during positioning operation, writing new positioning parameters and triggering the "Target Position Change Request" relay, can synchronously change speed, supports direction change (motor first stops urgently and then locates towards the new target position)-

Speed change during positioning operation, writing new target speed and triggering the "speed change request" relay to achieve real-time speed adjustment-

Speed control writes parameters such as target speed (negative speed corresponds to reverse rotation), acceleration and deceleration time, triggering the "start operation command" relay. The motor continues to rotate and needs to be terminated through "deceleration stop request" or "immediate stop request". Only incremental encoders are supported; Acceleration and deceleration curves are the same as positioning operations; Support normal startup or waiting for internal/external trigger startup

Speed change in speed control. During speed control operation, writing a new target speed and triggering the "speed change request" relay does not support direction change (need to slow down and stop first, then reset direction to start)-

Switching between speed and position control modes: During the operation of speed control, parameters such as target position, speed, acceleration and deceleration are written to trigger the mode switching command. The positioning operation can be set to normal switching or wait for external triggering switching when the instantaneous position is set to "0"; Support detection of Z-phase signal switching (Z-phase polarity and counting frequency need to be set)

Writing parameters such as target speed and acceleration/deceleration time in jog step, triggering the "positive jog step" or "negative jog step" relay. When the relay is disconnected, the motor decelerates and stops according to the parameters, which only takes effect when there are no errors, servo ON, positioning end, position control mode, and no other instructions are executed; Can only be terminated by "stop immediately", cannot be stopped by "slow down"

The emergency stop input module includes one emergency stop input (dedicated to the 1-axis connector, shared by both axes), which is a B-contact input and must be wired. Otherwise, the module will not work and the motor will stop immediately after triggering-

External contact input: 6 external contact inputs, functions can be defined through the "contact input mode" (such as limit, alarm, origin, trigger, etc.), polarity can be set separately, and status can be read through the application program-
