Use of the VLT

frequency converter’s internal PID regulator

with external set-point (0-10 V)
Feedback 0-10 bar ~ 4-20 mA
Min. speed = 10 Hz
Max. speed = 50 Hz

Example 7:

NB:

Screen for control cables must be

connected as described in the chapter on
EMC-correct installation.

All settings are based on factory settings, but
motor data (parameters 103-105) must be set
according to the motor connected

Connection examples

The following must be programmed:
