YASKAWA Varispeed f7 User Manual

2-26
* 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 2.20.
* 3. Pulse input specifications are given in the following table.
* 4. Use the photocoupler outputs when the minimum permissible load is 5 VDC or less and 10 mA or less.
