Figure 7-4 Three-wire Running Mode 2
The Xi (i=2 - 7) terminal is set to "9: three-wire run control".
The rising edge of K1 terminal indicates the running command; the disconnection of K2 terminal
indicates the forward direction command; the closing of K3 terminal indicates the reverse direction
command; when K3 disconnects, the inverter will stop.
Command channel selection
There are three different ways to set inverter running command.
0:Use operation panel to set running command Press the buttons on the operation panel, such as
Run (F 1), Stop (F 2) and LO/RE (F 3) to control the running, stop and forward/reverse rotation of
the inverter.
1:Use terminal to set running command The running, stop and forward/reverse rotation of the
inverter is performed by defining terminals X0 to X6. See P30.00 - P30.06 for description.
2:Use communication to set running command The running, stop and forward/reverse rotation of
the inverter is performed by Modbus communication. See Appendix Modbus Communication
Protocol.
5: PLC preset command When ProfiNet board card is configured, this control mode can be
selected.
6: SSL preset command When IO board card of SSI is configured, this control mode can be
selected.
This function is applicable to frequency reference. See group P10.00 function code for the option of
control mode.
0:Panel digital frequency reference Set the frequency reference by P40.00, and users can increase
or decrease the frequency by ▲ and ▼ keys during the running. The setting will remain unchanged
when the machine is shutdown; and when the power supply fails, this setting will not maintain
unchanged.
1:Digital multi-speed setting target velocity The digital multi-speed terminals 0 - 3 are valid, and
the frequency is determined by the combination of this terminal. See P41.00 - P41.15.
3:A0 analog target speed preset
