4.2 Speed Servo Mode
In speed servo mode, the DYN4 servo drive takes command from an external ±10VDC analog reference
voltage from the host controller to drive a linear proportional motor speed.
In speed servo mode, the torque output depends on the load on the servo motor and determined by the
motor feedback position. Design the system so it can withstand the peak torque of the motor in use.
█ Control Reference
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.
