5 Programming the control signal terminals
This section describes how to assign various functions to the
control signal terminals.
Overview
Table 9 provides an overview of the control signal terminals and a
brief description of the functions which you can assign to the
programmable digital inputs and outputs. For a detailed descrip-
tion of each function,
a

Digital inputs 1 to 8
Parameterizing PNU C01 to C08
REV
01
Anticlockwise operation
(start/stop)
REV input closed: motor starts up in an anticlockwise direction.
REV input open: controlled motor deceleration to stop (anticlockwise).
FW(D) and REV inputs closed simultaneously: controlled motor deceleration to stop.

For four fixed frequency stages (three programmable fixed frequencies and a setpoint value), two
fixed frequency inputs (3 = FF1 and 4 = FF2) 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 A38 is applied to the motor. Under PNU A39, you can select one of three different operating
modes for stopping the motor.
DB
07
External brake
When the DB input is active, DC braking can be carried out.
SET
08
Selection of the second
parameter set
Switching on SET allows you to select the second parameter set for setpoint 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 A
