*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. Do not use this power supply for supplying any external equipment. *3. When driving a reactive load, such as a relay coil with DC power supply, always insert a flywheel diode as shown in Fig 6 *4. Pulse input specifications are given in the following table: Flywheel diode External power: 30 VDC max. Coil The rating of the flywheel diode must be at least as high as the circuit volt- age. 1 A max. Fig 6 Flywheel Diode Connection 1.
In Fig 4 the wiring of the digital inputs S1 to S7 is shown for the connection of contacts or NPN transis- tors (0V common and sinking mode). This is the default setting. For the connection of PNP transistors or for using a 24V external power supply, refer to Table 3 . 2. A DC reactor is an option only for Inverters of 18.5 kW or less. Remove the short circuit bar when con- necting a DC reactor.
