7.1 Application example 1

The speed of a motor shall be controlled via the motor's potentiometer (hand) or using a analog signal via
an external control signal DC 0...10 V within the frequency range of 0...50 Hz.
ON and OFF via the digital input
−
Error message via relay output 1
−
Indication of operation via relay output 2
−
Note: With the settings for this application example, the assumption is made that the parameters use their de-
fault values and that the connected motor has been commissioned with the standard parameters.
