1.5.9 PID control valid terminal: Pr. 60 to Pr. 63 setting "14"
To exercise PID control, turn on the X14 signal. When this signal is off, ordinary
inverter operation is performed. For more information, refer to page 117.
1.5.10 PU operation/external operation switchover: Pr. 60 to Pr. 63
setting "16"
You can change the operation mode.
With "8" set in Pr. 79 "operation mode selection", turning on the X16 signal shifts the
operation mode to the external operation mode and turning off the X16 signal shifts it
to the PU operation mode. For details, refer to page 113.
