Failure diagnosis / error messages

Communication port error of DSCONTROL-WIN

When DSCONTROL-WIN is launched, the error ”Port not automatically detected” appears.
Is it a product defect?

It is not a defect of the product. It is an automatic search error of COM port number.
Please rewrite the port number manually according to the following procedure.

(1) Please open the device manager. (Enter the device manager in the search box on the task bar)
(2) Check the □ number of “SURUGA SEIKI DS102 USB Serial Port (COM □)” directly under the port
     (COM and LPT)
(3) Please open the setting file (DSControlWin.ini) in the following directory:
     C:\Program Files\SURUGA\DSControlWin with a text editor such as Notepad.
(4) Rewrite the value of Port Number with the COM port number confirmed by the device manager,
     close the file by overwriting it.
(5) Start DSCONTROL-WIN again.

[DS102 / DS112 Series] motor is not excited

The motor is not excited even when the power is turned on. The motor knob can be easily turned by hand.

【Possible cause】
Improper connection of motorized stage connection cable or power cable

【Action】
Check if the connection of motorized stage connection cable or power cable is correct.

[DS102 / DS112 series] The stage does not move

The power is on and the motor seems to be excited, but the stage does not move.

【Probable cause 1】
Emergency stop is working.
【Action 1】
Make sure that the "emergency stop input (EMS)" is not ON (the 2 pins of EMS connector are not open).
Please refer to DS102/112 Operation Manual page 70.

【Probable cause 2】
The setting of the DIP switch on the back is incorrect.
【Action 2】
Check the DIP switch setting in the instruction manual (page 119).

【Probable cause 3】
The sensor logic setting is incorrect.
For motorized rotary stages (KRE series), it is necessary to set the limit sensor to be normally open.
【Action 3】
Please confirm the sensor logic setting of the parameter.

【Probable cause 4】
The current down function is "OFF" (in the case of a normal driver).
【Action 4】
Switch the current down function to "ON". Please refer to the instruction manual page 94.

[DS102 / DS112 Series] actual travel distance is inconsistent with the setting

Actual travel distance does not match with the setting distance

【Probable Cause 1】
Unit setting error of parameters.
【Action 1】
Value to be set to STANDARD (ST) shall be the amount of movement per pulse of "full step setting,"
even if you change the setting of number of divisions.
Please set the value of each stage by referencing catalog, etc.

【Probable cause 2】
Only number of divisions on handy terminal is changed.
* In the case of micro-step type
【Action 2】
In the case of micro-step type (such as DS102MS), if you want to change the number of divisions,
please change both the switch settings and the controller of the handy terminal.

[DS102 / DS112 series] The motor is hot while stopping

Even when the stage is not moving, the motor is very hot as the current does not decrease.

【Possible cause】
The current down function is "OFF" .
【Action】
Switch the current down function to "ON".

Motor (motorized stage) is out of step

The stage does not move and there is a noice from motor. It seems out of step.

【Probable cause 1】
The load is large. Or, the load fluctuation is large.
【Action 1】
Check if there is a large load fluctuation during operation.
If there is no problem by lowering the motor rotation speed which has higher torque,
it is necessary to review the load conditions.

【Probable cause 2】
The start pulse speed is too high.
【Action 2】
Reduce the start pulse speed, and reset it to a time that can be stably started.

【Probable cause 3】
The acceleration (deceleration) time is too short.
【Action 3】
Increase the acceleration (deceleration) time, and reset it to a time that can be stably started.

Motor vibration is large

I feel that the vibration of the motor is too big.

【Probable cause】
The motor of the motorized stage is resonating.

【Action】
When the driving pulse speed is changed and the vibration becomes smaller, the motor is
likely to be resonating.
Change the setting of driving pulse speed or install a clean damper (commercially available) to
suppress vibration.

Motor on motorized stage is too hot

It is so hot that I cannot even touch the motor.

【Probable cause 1】
The operation time is long.
【Action 1】
Reduce the operating time or increase the stop time. Please use motor case temperature
at 100 degrees or less.

【Probable cause 2】
The current down function is "OFF".
【Action 2】
Switch the current down function to "ON".

[DS102 / DS112 series] It does not move if multiple units are linked

I tried to link two controllers to move the 3 axes, but they did not move at all.

【Possible cause 1】
The setting of the DIP switch(slave/master) on the back is incorrect.
【Action 1】
Check the DIP switch setting in the instruction manual (page 119).

【Possible cause 2】
The power on procedure is incorrect.
【Action 2】
Please turn the power on in the following series: slave 2 > slave 1 >Master.

[DS102 / DS112 series] Motorized rotary stage: KRE series does not move

I tried to operate KRE06360/04360 with DS102 (112) but it does not move. Is it a breakdown?

When using the KRE series with the DS102 / 112, set the limit sensor logic to A (Normal Open).
