The setting frequency can be adjusted with command of Up / Down / Reset, by
setting the status of digital inputs. The setting frequency will increase with Up
command active, decrease with Down command active, reset to '0' with Reset
command active.
To use this function, take the following steps:
Step 1: Set the frequency setting source
Set either E0.00 'First frequency setting source' or E0.02 'Second frequency set-
ting source' to '11: Digital input Up / Down command'. If the active frequency
command input channel ([E0.00] or [E0.02]) is set to 11, the [E1.17] will be tak-
en as the current set frequency.
Step 2: Select any 3 digital inputs and define functions accordingly
Set any 3 digital inputs of E1.00... E1.04 and H8.00...H8.04 to '20: Frequency Up
command', '21: Frequency Down command' and '22: Up / Down command reset'.
Step 3: Set the change rate and initial frequency for Up / Down operation
Set E1.16 'Digital input Up / Down change rate' and E1.17 'Digital input Up /
Down initial frequency' according to the application.
Example:
[E1.00] = 20, [E1.01] = 21, [E1.02] = 22
