54
2CH 09 Second time ramp Activates the second acceleration and deceleration time with PNU A92 and PNU A93 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.
SET3 17 third parameter set
With the third parameter set, you can change the frequency inverter over to operate a third motor.
Parameters in the third parameter set are identified by a leading “3”, e.g. : PNU A301
RST 18 Reset
To acknowledge a fault message, switch on the RST input. If a reset is initiated during operation,
the motor will coast 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
CAS 26 Tacho-generator with
vector control
When this input is activated, the speed controller operates with the values set under PNU H070,
H071 and H072.
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 through
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 fixed frequency
selection
Motor control using a fixed frequency.
OLR 39 Current limit changeover
Change over to further current limitation parameters: PNU b024, b025, b026 (default: PNU b021,
b022, b023)
TL 40 Torque limitation active
Only with vector control
TRQ1 41 Torque limitation 1
active
Inputs TRQ1 and TRQ2 provide bitwise control of the torque limits for the four quadrants.
TRQ2 42 Torque limitation 2
active
PPI 43 P or PI control
Only with vector control
