Torque Servo Mode
In torque servo mode, the DYN4 servo drive takes command from an external
±
10VDC analog reference
voltage from the host controller to drive a linear proportional output current.
█
Control Reference - [ H01 ] Capacity Model: DYN4 - H01
The DYN4 servo drive accepts FORWARD reference as CLOCKWISE motor shaft rotation as viewed from
motor shaft side.
Positive reference voltage rotates the servo motor in the FORWARD (CLOCKWISE)
direction and negative reference voltage rotates the servo motor in the REVERSE (COUNTER CLOCK
-
WISE) direction.
