Motor control (MCTRL)
Encoder/feedback system
5.10 Encoder/feedback system
This function extension is available from version 02.00.00!
The speed feedback mandatory for the V/f control (VFCplus + encoder)
can be fed in at the
digital input terminals (DI1/DI2) via an HTL encoder.
 In order that the HTL encoder can be evaluated correctly, the digital input terminals
(DI1/DI2) must be configured as frequency inputs.Configuring DI1 and DI2 as
frequency inputs ( 134)
 The actual speed value (C00051
) is also calculated when motor control without
encoder feedback has been selected if an encoder is connected and "1: Encoder signal
FreqIn12" has been selected in C00495
.

 Danger!
• For (open circuit) monitoring of the encoder, it is recommended to set the
"Fault" response (Lenze setting) in C00586
for safety reasons!
• In order to prevent interference injections when using an encoder, only use
shielded motor and encoder cables.
• Make sure that the maximum input frequency of 10 kHz at the frequency
inputs is not exceeded when the V/f control (VFCplus + encoder)
is used.
• When evaluating a single-track encoder, make sure that the sign has been
selected correctly. Otherwise, there is a risk that the motor may overspeed.
