03-0X =26: Pulse Input Frequency
To following parameters have to be set to use the Pulse Input Frequency function.
00-05=7: Pulse with speed control
03-02=26: Pulse input frequency
03-28=100.0 ~ 1000.0%: pulse input gain setting
Inverter reference frequency= (Pulse input frequency) x (03-28) Hz, reference frequency limit is the inverter
frequency upper limit
Example 1:
Pulse input frequency is 20Hz, frequency upper limit is 50Hz (00-12=50.00), and 03-28=100.0, Inverter reference
frequency is 20.00Hz.
Example 2:
Pulse input frequency is 50Hz, frequency upper limit is 50Hz (00-12=50.00), and 03-28=100.0, Inverter reference
frequency is 50.00Hz.
Example 3:
Pulse input frequency is 55Hz, frequency upper limit is 50Hz (00-12=50.00), and 03-28=100.0, Inverter reference
frequency is 50.00Hz.
Example 4:
Pulse input frequency is 599Hz, frequency upper limit is 599Hz (00-12=599.00), and 03-28=20.0, Inverter
reference frequency is 599 x 0.2 = 119.9Hz
Notes:
Pulse Input frequency range is 0.05~25.00 kHz.
Only terminal S3 can be used for pulse input.
Digital Inputs configured for PNP
: (set switch JP1 to PNP)
The pulse output terminal (Y0) of PLC needs to connect to S3 terminal of inverter.
The common terminal of the pulse generator (e.g. PLC) output needs to be connected to the +24V terminal of
the inverter.
Digital Inputs configured for NPN
: (set switch JP1 to NPN)
The pulse output terminal (Y0) of PLC needs to connect to S3 terminal of inverter.
The common terminal of the pulse generator (e.g. PLC) output needs to be connected to the COM terminal of
the inverter.
