* 1. The
default settings are given for terminals S3 to S7. 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 2.24.
* 3. Pulse
input specifications are given in the following table.
