RV FW
Input FW closed: Motor starts with forward running direction.
Input FW open: Motor decelerates from forward running.
(same for reverse run using input RV)
Inputs FW and RV both closed: motor decelerates.

Example:
4 multistage speeds
Analog set value
2 multistage inputs (CF1 and
CF2) are necessary for 4
different multistage speeds
(3 programmable multistage
speeds plus 1 set value).

JG
(06)
Jogging run
The jogging run activated using the terminal JG may serve for setting up a machine
in manual operation mode. When a forward or reverse run command is given, the
frequency configured using A 38 is then sent to the motor. For motor stop, one of
three operating modes can be chosen by configuring A 39 .
PTC
(19)
Connection of exter-
nal PTC thermistor
Only digital input 5 can be programmed as a PTC thermistor input (using C 05 ).
The terminal L serves as common for the thermistor input.
AT
(16)
Activate input OI (cur-
rent set value 4-20mA) When the AT input is activated, then the set value will be a 4-20mA current
that has to be supplied at the terminals OI and L.
2CH
(09)
2. stage acceleration /
deceleration
Using this input the second stage acceleration and deceleration time
configured using A 92 and A 93 is activated.
FRS
(11)
Free run stop
function
When the terminal FRS is turned on, frequency to the motor is
switched off and the motor runs free.
EXT
(12)
External trip
When the terminal EXT is turned on, the inverter enters the trip state, stops output
to the motor, and displays E 12 . The trip condition can be acknowledged, among
others, using the RS input.
USP
(13)
Prevention of restart
When the USP input is on, the motor does not restart when power supply recovers
following a power supply failure and a running command is active at the same time.
RS
(18)
Reset
A trip can be acknowledged by activating the RS input. If a reset is given during
normal inverter operation, the motor runs free. The RS input is always a normally
open contact and cannot be configured as normally closed input.
