Install appropriate protective circuitry for the servo drive. Minimum wiring requires a 20A ~ 400V fuse or moulded case circuit breaker before the power is
fed into the servo drive.
Recommended: An EMI noise filter should be connected between the AC Input power and Logic Power Terminal.
This will eliminate external electrical noise disturbances.
Step 5: Grounding
Ensure that the power supply ground terminal and the servo motor ground terminal
are securely connected to the DYN3 servo drive’s grounding terminals.

Step 6: Connect I/O
The DYN3 servo drive accepts standard differential PULSE/SIGN pulse train commands, or analogue +/-10VDC Speed / Torque reference commands. Terminal JP4
should be used to make appropriate connections with external host controllers. Refer to DYN3 servo drive manual for detailed descriptions of each I/O.

Step 7: Power Up
Apply power to the Logic Control Power and Main Control Power of the servo drive. The S1 status indicator lamp should be lit GREEN and the S2 status indicator
lamp should be OFF.
The servo motor should be clamped (locked) and ready for command from the host controller.
Step 8: PC Communication
Connect the CA-MRS232-6 tuning cable from servo drive JP2 terminal to the controller PC. The DMMDRV program can also support RS232-USB converters if
necessary.
Open and launch the DMMDRV3.exe program:
Select ComSet > ComPort from the main program dialog box function bar:
Select the appropriate Communications Port (COM). Check your PC’s Device Manager to find the communication power number of the RS232 cable. Press Change
Port until the correct port is selected. Then press OK to confirm and save selection.
Select ServoSetting > DYN3-Driver. The main servo drive tuning and testing screen will open:
Figure 5. JP4 External I/O Terminal

Press Read on the Setting driver parameters and mode dialogue box. After approximately 1~2 seconds, the on-screen parameters will change according to the current
internal parameter settings of the connected servo drive. Ensure that the Driver Status indicates ServoOnPos to indicate that the drive has closed the position loop
with the motor and is fully operational. The Servo drive is now fully communicating with the host PC.
The factory servo drive default PID servo Gain settings should be:
Main Gain –38
Speed Gain –38
Integration Gain –38
If the settings are different, change the parameters to the above. Once testing is complete, these settings can be changed according to the load mass characteristics of
the servo motor.
Use the on-screen slider to change each setting to “38”. Then click Save All to save these parameters into the EEPORM memory of the servo drive.
To confirm that these parameters are save into the servo drive, click Default Cons to reset the on-screen settings to the default parameters (This does not affect the
parameters in the servo drive since it is not saved). Click Read, then the previously saved settings should now be displayed on the screen.

Step 9: Test Movements
Warning: During Test movement procedures, the servo motor can rotate very quickly in either direction.
Ensure that the servo motor is free to rotate and no dangerous objects are attached to or near the motor shaft.
Select RS232 under the command input mode option. Select Position Servo in the Servo mode option.
Click Save All
Under the Test Motions menu, the user can select one of 4 test motions to jog or move the servo motor. Only one test motion profile can be run at a time, use the radio
buttons below each section to select the movement profile.
Trimming
The absolute position of the servo motor can be trimmed from 1 to 4096 reference units. Since the ABS-14-0
absolute encoder has a resolution of 16,384ppr, this corresponds to a maximum of 90° movement when
trimming.
Sinusoidal
The motor moves along an oscillated smooth sinusoidal S-curve. The frequency slider controls the frequency of
oscillation and the amplitude slider controls the travel amplitude per oscillation period.
Step
The motor moves along an oscillated “stepped” S-curve without acceleration/deceleration profiles. The frequency
slider controls the frequency of oscillation and the amplitude slider controls the travel amplitude per oscillation
period.
Constant Speed (JOG)
The motor is run at a constant speed set by the slider. The direction of rotation can be changed by the Reverse
Turn button and the rate of acceleration/deceleration during direction switching is controlled by the Max
Acceleration parameter. Note that the servo drive will throw a “Lost Phase” protective alarm if the motor is
commanded to run above its maximum speed.
Step 10: Host Controller Command
The servo drive should be set and saved into the appropriate command input mode according to the command mode of the host controller. For example, a host
controller using PULSE/SIGN command mode should have the servo drive saved into the Pulse/Dir command input mode and Position Servo mode. Use the
appropriate communication ports from JP4 to communicate with the host controller.
To Host Controller:
PLC
CNC Control Panel
Pulse Generator
