1.1 Explanation of the Parameters
P1xx Setpoints / Integrators
P100 Setpoint
source • FREQUENCY INPUT: Setting the parameter P100 Setpoint source to the function
"Frequency input" causes the set speed to be set via digital input DI04 in the form of
a frequency. Input DI04 can be used as "frequency input." The binary input works
with PLC-compatible input signals that are specified as follows:
– –3 ... +5 V -> 0 level
– +13 ... +30 V -> 1 level
– This means an HTL encoder can be connected to the input to serve as a refer-
ence input variable encoder. The pulses from this encoder are then counted via
input DI04 and a setpoint is calculated for the unit. The pulse duty factor (pulse
width of the high and low signal) should be about 1 : 1. The factor determines the
rising edge and the falling edge of the input signal. The P102 Frequency scaling
is used to determine at which input frequency the system setpoint 100 % is
reached. The reference of the system setpoint is set via parameter P112 AI1
Operating mode . The direction of rotation is set via the binary inputs CW/STOP
and CCW/STOP.
Resolution
Setpoint cascade:
Example:
A setpoint transmitter with the value range 1 ... 50 kHz is to specify the motor speed
from 30 ... 1500 rpm.
To do so, the following parameters must be set:
• P102 Frequency scaling: 50 kHz
• Operation mode setpoint P112: 3000 rpm
• Setpoint scaling P110: 0.5
Frequency scaling Minimum scan frequency Resolution
25 ... 65 kHz 20 ms 50 Hz
12.5 ... 24.99 kHz 40 ms 25 Hz
10 kHz 60 ms 16.7 Hz
1 kHz 500 ms 2 Hz
P110: Gain 0.1 ... 1 ... 10
P302: Maximum speed in rpm
P102: Frequency scaling 1 ... 65 kHz
P112: Operation mode setpoint
