* 1. For a 3-wire sequence, the default settings are a 3-wire sequence for S5, multi-step speed setting 1 for S6 and multi-step speed setting 2 for S7.
* 2. When driving a reactive load such as a relay coil, always insert a flywheel diode as shown in Fig 2.18.
* 3. Use the photocoupler outputs when the minimum permissible load is 5 VDC or less and 10 mA or less.
External power:
48 V max
