Selecting the operation mode, following software enabling (1.131) and hardware enabling, the drive
controller runs as follows:
2 = preset speed in inverter software, with the frequencies defined in parameters 2.051 and
Minimum frequency
2.050 Preset speed mode in software
1 = Digital Input 1, 2
►
preset Frequency 1-3 (2.051 to 2.053)
2.051 Preset speed 1 in software
XX = Set the frequency, it could not be lower than minimum speed and higher than maximum speed.
2.052 Preset speed 2 in software
XX = Set the frequency, it could not be lower than minimum speed and higher than maximum speed.
2.053 Preset speed 3 in software
XX = Set the frequency, it could not be lower than minimum speed and higher than maximum speed.
1.020 Minimum speed
This parameter must not be changed, risk of damage to the machine!
