54
2CH
09
Second time ramp
Activates the second acceleration and deceleration time with PNU A092 and PNU A093
respectively
FRS
11
Controller inhibit
(free run stop)
When FRS is switched on, the motor is immediately switched off and coasts to a stop.
EXT
12
External fault
When the EXT input is switched on, the fault signal activates PNU E12 and the motor switches off.
The fault signal can be acknowledged, for example, with the RST input.
USP
13
Unattended start
protection
When the USP input is switched on, unattended start protection is active. This prevents a motor
restart when the voltage recovers after a mains failure while a start signal is present.
CS
14
Heavy mains starting
For starting drives with extremely high starting torques
SFT
15
Parameter protection
The parameter protection, which is activated by switching on the SFT input, prevents loss of the
entered parameters by inhibiting write operations to these parameters.
AT
16
Setpoint input OI
(4 to 20 mA) active
When the AT input is switched on, only setpoint value input OI (4 to 20 mA) is processed.
RST
18
Reset
To acknowledge an error message, switch on the RST input. If a reset is initiated during operation,
the motor coasts to a stop. The RST input is a make (NO) contact; it cannot be programmed as a
break (NC) contact.
STA
20
Pulse start (3-wire)
These settings enable three-wire control of these three functions.
STP
21
Pulse stop (3-wire)
F/R
22
Direction of rotation
(3-wire)
PID
23
Activation of PID control
Switching the internal PID controller on and off
PIDC
24
Resetting the integral
component of the PID
control
UP
27
Acceleration (motor
potentiometer)
When input UP is switched on, the motor accelerates (available only if you have specified the
frequency setpoint with PNU F001 or A020).
DWN
28
Deceleration (motor
potentiometer)
When input DWN is switched on, the motor decelerates (available only if you have specified the
frequency setpoint with PNU F001 or A020).
UDC
29
Reset frequency (motor
potentiometer)
When the UDC input is switched on, the motor is controlled with the frequency set under
PNU A020 (available only if you have specified the frequency setpoint with PNU F001 or A020).
OPE
31
Setpoint value via
keypad
When this input is switched on, the frequency inverter operates with the frequency set at
PNU F001.
SF1 to
SF7
32 to 38
Bitwise frequency
selection
Motor control using a fixed frequency.
OLR
39
Current limit changeover
Changeover to other current limit parameters: PNU b024, b025, b026
(default setting: PNU b021, b022, b023)
NO

FWD = clockwise
operation (start/stop)
FW(D) input closed: motor starts up in a clockwise direction.
FW(D) input open: controlled motor deceleration to stop (clockwise).
FW(D) and REV inputs closed simultaneously: controlled motor deceleration to stop.
