6. Pulse input’s filter time: 03-34 (if the pulse input is unstable due to the interference, increase value.)
7. Pulse output function selection: 03-35=1 (Pulse output is output frequency
8. Scale pulse output parameter 03-36 to 100% of output frequency
Inverter #1 parameter settings: Frequency reference from analog signal
1. Frequency reference selection: 00-05=1 (Analog input)
2. Pulse output function selection: 03-35=1 (Pulse output is output frequency
3. Scale pulse output parameter 03-36 to 100% of output frequency
Inverter #2: parameter settings:
1. Frequency reference selection: 00-05=4 (Pulse input)
2. Pulse input’s function selection: 03-30=0 (General pulse input)
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 filter time: 03-34 (if the pulse input is unstable due to the interference, increase value.)
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)
Example C: Synchronized operation using pulse input
Figure 4.4.33: Synchronized operation of using pulse input
Connect pulse signal of an external pulse generator to the pulse input terminal PI of multiple follower inverters for
output speed synchronization.
Follow inverter #1 and Follower #2 parameter settings:
1. Frequency reference selection: 00-05=4 (Pulse input)
2. Pulse input’s function selection: 03-30=0 (General pulse input)
3. Set one of the Multi-function inputs Sn: 03-00 ~ 03-07=32 (Synchronization command)
Example D: Synchronized operation of using pulse output master follower
