Lenze i550

Details
The digital inputs must be congured such that they detect the frequency input signal
(0x2630:002 (P410.02)).
0x2630:002
a)
Input funcon 0x2630:002 (P410.02) = "Pulse train [2]"
(DI4 = input for pulse train, DI3 = normal digital input)
This selecon congures the digital inputs to detect the frequency signal, whereby DI4 is
congured to detect the frequency input signal (pulse train).

Input funcon 0x2630:002 (P410.02) = "Pulse train/direcon [3]"
(DI4 = input for pulse train, DI3 = input for specicaon of direcon)
This selecon congures the digital inputs to detect the frequency and direconal signals,
whereby the digital input DI4 is congured to detect the frequency input signal (pulse
train) and DI3 is congured to detect the direconal signal.

Scaling
The scaling of the frequency signal in relaon to the setpoint range takes place in two steps
can be congured as follows:
•
Idenfy the minimum and maximum frequency of the frequency signal (pulse train).
•
Set the minimum frequency value (Hz). 0x2640:001 (P415.01)
When DI3 is used to control the pulse train 0x2630:002 (P410.02)= [3], this
value must be congured to the corresponding NEGATIVE pulse frequency
value.
•
Set the maximum frequency value (Hz). 0x2640:002 (P415.02)
Area
Congure the range for the setpoint, which corresponds to the minimum and maximum fre-
quency of the frequency signal (pulse train).
Frequency setpoint:
•
Set minimum desired motor frequency (Hz). 0x2640:003 (P415.03)
•
Set maximum desired motor frequency (Hz). 0x2640:004 (P415.04)
Process control:
•
Set minimum desired PID setpoint (PID controller). 0x2640:005 (P415.05)
•
Set maximum desired PID setpoint (PID controller). 0x2640:006 (P415.06)
