gefran VDI100 Series

Refer to Table 4.4.10 for pulse output function selection overview.
Code Parameter Name / Range
03-36 Scale of pulse output
1~32000 Hz
Pulse output scaling, 100% = Maximum pulse frequency (see table 4.4.10).
Note: When setting 03-35 to 2 (output frequency) and setting 03-36 to 0 (0 Hz), PO’s pulse output and the inverter output
frequency are sync.

Note: Selection 1~4 are related to the motor speed, 5 and 6 are related to PID and 7 is related to PG.
Setup the pulse output
Use 03-36 (pulse output scale) to set the pulse output frequency to100% signal value of the selected item.
Please refer to the gure 4.4.29.

When setting 03-35 to 2 (output frequency), PO’s pulse output and the inverter output frequency are sync.
Scale of pulse output is equal to the value of 03-36.
For the pulse output signal level, please refer to gure 4.4.30.

When 03-35 = 7 (PG pulse monitoring output), PG pulse output scaling is internally set 1:1, independent of the
scaling set in parameter 03-36.
Note: When pulse output function is active, it is required to use the external pull-up resistor at the terminal of PO (the upper
limit current of PO is 50mA and 48V).
