ontrol Output Circuits
The specifications of the control output circuits are shown below.
*1. When you use an output signal to drive a relay directly, always insert a diode as shown in the above figure.
Use a high-speed diode
When the brake control is performed with the external brake interlock output (EXTBKIR) allocated to
the general output, the connection must be as shown below.
*1. We recommend you to use the OMRON MY Relay (24V type) for the external relay.
*2. We recommend you to use the Panasonic Corporation ERZ-V07D390 for the surge suppressor.
*3. Always insert a diode as shown in the above figure.
We recommend you to use the Sanken Electric Co., LTD. RU2 for the diode.
*4. Do not share the external power supply.
