Output signal
Output terminal assignment during dancer control (PID control) operation
PID signal turns on during dancer control (PID control) or at a stop by PID control (in the status PID op-
eration being performed inside) (The signal is off during normal operation.)
For the terminal used for PID signal output, assign the function by setting "47 (positive logic) or 147
(negative logic)" in any of Pr. 190 to Pr. 192 "Output terminal function selection".
PID monitor function
The PID control set point and measured value can be output to the operation panel monitor display
and terminal AM.
For each monitor, set the following value in Pr. 52 "DU/PU main display data selection" and Pr. 158
"AM terminal function selection".
Priorities of main speed command
The priorities of the main speed speed command source when the speed command source is external
are as follows.
JOG signal > multi-speed setting signal (RL/RM/RH/REX) > 16 bit digital input (option) > terminal 2
The priorities of the main speed speed command source when "3" is set in Pr. 79.
Multi-speed setting signal (RL/RM/RH/REX) > set frequency (digital setting by PU, operation panel)
Terminal 4 can not be selected as the main speed speed command even when AU terminal is turned
on.
Even when a remote operation function is selected by setting a value other than "0" in Pr. 59, com-
pensation of the remote setting frequency to the main speed is ignored (changes to 0).
NOTE
Changing the terminal function using any of Pr. 178 to Pr. 184, Pr. 190 to Pr. 192 may affect the
other functions. Make setting after confirming the function of each terminal.
