Extension cable

There are cables that connect the actuator and driver, and there are communication cables that connect the driver and personal computer.

Application cable Model
For motors EWC-MB**-A06-TN2
For encoders EWB-F**-M0809-3M14
For EIA-232 HDM-RS232C (cable length: 1.5m)

Connectors

This connector is used to connect each model driver. There are 2 types of connectors for the driver for different set types.

4 type set (CN1, CN2, TB1, TB2)
Model: CNK-HA68-S1
2 type set (CN2, TB2)
Model: CNK-HA68-S2 (If you will use an extension cable, this model must be used.)
  • * The extension cable for the encoder is required to connect with the driver.

Dedicated communication software (provided free of charge): PSF-520

This dedicated communication software is used to set/change parameters in the HA-680 driver.
The dedicated communication software can be from our website at [http://www.hds.co.jp/english/]. Perform a full parameter setting for the HA-680 driver using the PSF-520 dedicated communication software.

  • Note 1 The table shows the values of the output shaft containing HarmonicDrive® efficiency.
  • Note 2 All specifications are applicable for actuators combined with an application driver and actuators mounted on an aluminum radiation plate of size: 150 x 150 x 6(mm).
  • Note 3 * denotes the values for saturated actuator temperature. Other values are for actuator temperature of 20°C. All values are typical.
  • Note 4 The inertia moment is the total value of the motor shaft and HarmonicDrive® moment of inertia values converted to the output side.
  • Note 5 The encoder resolution is (motor shaft encoder resolution when multiplied by 4) x (reduction ratio).
