Terminal 4: 0–5V DC, 0–10V DC, 0/4–20mA
Entered from operation panel and parameter unit
Forward and reverse rotation or start signal automatic
self-holding input (3-wire input) can be selected.
Any of 7 signals can be selected using parameters 178 to 184 "Input terminal function selection":
multi-speed selection, remote setting, stop-on contact selection, second function selection, termi-
nal 4 input selection, JOG operation selection, PID control valid terminal, brake opening comple-
tion signal, external thermal input, PU-external operation switchover, V/f switchover, output stop,
start self-holding selection, forward rotation, reverse rotation command, inverter reset, PU-NET
operation switchover, external-NET operation switchover, command source switchover, inverter
operation enable signal, and PU operation external interlock
Maximum/minimum frequency setting, frequency jump operation, external thermal relay input
selection, automatic restart after instantaneous power failure operation, forward/reverse rotation
prevention, remote setting, brake sequence, second function, multi-speed operation, stop-on
contact control, droop control, regeneration avoidance, slip compensation, operation mode selec-
tion, offline auto tuning function, PID control, computer link operation (RS-485)
Selection can be made from inverter operation, up-to-frequency, overload alarm, output fre-
quency detection, regenerative brake prealarm, electronic thermal relay function prealarm, inver-
ter operation ready, output current detection, zero current detection, PID lower limit, PID upper
limit, PID forward/reverse rotation output, brake opening request, fan alarm (FR-E720S-050 or
more, FR-E740-040 or more), heatsink overheat pre-alarm, deceleration at an instantaneous
power failure, PID control activated, during retry, life alarm, current average value monitor,
remote output, alarm output, fault output, fault output 3, and maintenance timer alarm using
Pr. 190 to Pr. 192 "Output terminal function selection".
Selection can be made from output frequency, motor current (steady), output voltage, frequency
setting, motor torque, converter output voltage, regenerative brake duty, electronic thermal relay
function load factor, output current peak value, converter output voltage peak value, reference
voltage output, motor load factor, PID set point, PID measured value, output power 0 to 10VDC
using Pr. 158 "AM terminal function selection".
