*1 | Figure | ||||
When the PLC power supply common may be connected to the drive 11 terminal to input analog frequency setting | |||||
| signals from the PLC, use this connection and set the SW7 switch 1 to EXT and 2 to PLC to prevent the FWD and | ||||
| REV terminals from turning on due to sneak path current when the PLC power is turned off. | ||||
*2 | With this connection, the power is supplied from the PLC power supply to the external thermal O/L relay. So, OH2 trip | ||||
| is activated by PLC | ||||
*3 | To prevent drive trip with OH2 when the PLC power being turned off, do not select the THR terminal function and use | ||||
| the drive electronic thermal O/L relay. | ||||
*4 | When the X3 terminal is used as the PLC terminal, no function that can be set with E03 can be used. The X3 terminal | ||||
| is dedicated to the PLC. |
