gefran VDI100 Series

Master inverter parameter settings:
1. Pulse output function selection: 03-35=1 (Pulse output is output frequency
2. Scale pulse output parameter 03-36 to 100% of output frequency
3. Set one of the Multi-function inputs Sn: 03-00 ~ 03-07=32 (Synchronization command)
Follower inverter parameter settings:
1. Frequency reference selection: 00-05=4 (Pulse input)
2. Pulse input’s function selection: 03-30=0 (Frequency command)
3. Pulse input scale: 03-31 (set the number of pulse in Hz to match maximum output frequency, 01-02)
4. Pulse input gain: 03-32 (Set the input gain of the pulse frequency set by 03-31)
5. Pulse input bias: 03-33 (Set the input bias of the pulse frequency set by 03-31)
6. Pulse input’s lter time: 03-34 (if the pulse input is unstable due to the interference, increase value.)
7. Set one of the Multi-function inputs Sn: 03-00 ~ 03-07=32 (Synchronization command)
Code Parameter Name / Range
03-37 Timer ON delay (DIO)
0.0~6000.0 s
03-38 Timer OFF delay (DIO)
0.0~6000.0 s
Enable the timer function be setting one of multi-function input parameters 03-00~03-07 (S1 to S8) to 35 (timer
function input) and one of multi-function output parameters 03-11, 03-12 (R1A-R1C to R4A- R4C and PH1 to
PH4) to 27 (timer function output).
The timer function can be used to implement a timer relay. Use timing parameter 03-37 and 03-38 to set the
timer ON / OFF delay.
Timer output is turned ON when the multi-function timer input is ON for the time specied in parameter 03-37.
Timer output is turned OFF after the multi-function timer input is turned OFF for the time specied in parameter
03-38.

Brake Release Function
It is required to be with the frequency agree function, as the following gure:
When the inverter starts running, if the output frequency > 03-13, and both frequency detection level and output
torque > torque detection level (03-41), it will delay the time of 03-42 to release brake.
