For four fixed frequency stages (three programmable fixed frequencies and a setpoint value), two
fixed frequency inputs (3 = CF1 and 4 = CF2) are required (2

=4).
JOG 06 Jog mode The jog mode, which is activated by switching on the JOG input, is used, for example, for setting
up a machine in manual mode. When a start signal is received, the frequency programmed under
PNU A038 is applied to the motor. Under PNU A039, you can select one of three different
operating modes for stopping the motor.
DB 07 DC braking
After the DB input has been enabled, DC braking is carried out.
SET 08 Selection of second
parameter set
Switching on SET allows you to select the second parameter set for reference frequency, torque
boost, first and second acceleration/deceleration ramp and other functions. Parameters in the
second parameter set are identified by a leading “2”, e.g. PNU A201
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 (free run stop) is switched on, the motor is immediately switched off and coasts to a
stop.
EXT 12 External fault message When the EXT input is switched on, the fault signal activates PNU E012 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.
SFT 15 Parameter access inhibit 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 Reference input OI (4 to
20 mA) active
When the AT input is active, only the reference 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.
PTC 19 Connection for a PTC
thermistor
Only digital input 5 can be programmed as a PTC thermistor input with PNU C005. Use terminal
L as the reference potential.
STA 20 Three-wire control, Start
signal
1) A state change (ON/OFF) during operation
causes a change in the direction of rotation
2) Open circuit protection (automatic motor
stop)
3) Pulse
STP 21 Three-wire control, Stop
signal
F/R 22 Three-wire control,
direction of rotation
