Input from the PU, with selectable frequency setting increments.
Forward and reverse rotation or start signal automatic self-holding input (3-wire input) can be selected.
Using Pr.178 to Pr.182 (input terminal function selection), the signal can be selected from the
Multi-speed selection, Remote setting, Second acceleration/deceleration function selection, Terminal 4
input selection, JOG operation selection, PID control valid terminal, External thermal relay input, Output
stop, Start self-holding selection, Forward rotation command, Reverse rotation command, Inverter reset,
Traverse function selection.
Maximum frequency, minimum frequency, frequency jump operation, external thermal relay input
selection, automatic restart after instantaneous power failure operation, forward/reverse rotation
prevention, remote setting, second acceleration/deceleration function, multi-speed operation,
regeneration avoidance, slip compensation, operation mode selection, offline auto tuning, PID control,
computer link operation (RS-485 communication), Optimum excitation control, power failure stop,
MODBUS RTU, increased magnetic excitation deceleration.
Using Pr.195 output terminal function selection, the signal can be selected from the following:
Inverter running, Up to frequency, Overload warning, Output frequency detection, Electronic thermal O/
L relay pre-alarm, Inverter operation ready, Output current detection, PID lower limit, PID upper limit,
PID forward/reverse rotation output, Heatsink overheat pre-alarm, During deceleration at occurrence of
power failure, During PID control activated, PID output interruption, During retry, Alarm output, Fault
output, Fault output 3.
Selectable from the following:
output frequency, output current(steady state), output voltage, frequency setting, cumulative
energization time, actual operation time, converter output voltage, electronic thermal relay function load
factor, motor load factor, PID set point, PID measured value, PID deviation, inverter I/O terminal monitor,
output power, cumulative power, motor thermal load factor, inverter thermal load factor.
Fault record is displayed when a protective function is activated. Past 8 fault records are stored.
(output voltage, output current, frequency, and cumulative energization time right before the protective
function is activated.)
