PLC Input
It is required to be with the software of Drive Link. PLC software program conducts the ladder diagram editing.
When the signal output conducts, it will be transmitted to the inverter to be active.
03-0X =25:
Pulse Width Measurement
Can only be used for terminal S3 (03-02=25) for pulse width measurement functions.
To following parameters have to be set to use the pulse width function.
00-05=7: Pulse with speed control
03-02=25: Pulse input width measure
03-27=0.05 ~ 25 kHz: pulse input frequency
03-28=100.0 ~ 1000.0%: pulse input gain setting
Inverter reference frequency= Duty cycle x (00-12) x (03-28) Hz, and below the frequency upper limit
Note:
In this mode, the frequency range of pulse input is 0.01 ~ 0.20 kHz.
Example:
To use the pulse input as a speed reference set the following parameters:
00=05=7, 03-0X=26
,
X=0~6 (except select 2), 03-27=pulse input frequency
03-28=100.0 (adjust as required)
Pulse input frequency is 200Hz, set 03-27=0.20kHz.
Example 1:
Pulse input frequency is 200Hz (03-27=0.20), duty cycle is 50%, frequency upper limit is 50Hz (00-12=50.00),
and 03-28=100.0. Inverter reference frequency is 50% x 50.00=25.00Hz
Example 2:
Pulse input frequency is 200Hz (03-27=0.20), duty cycle is 30%, frequency upper limit is 50Hz (00-12=50.00),
and 03-28=200.0. Inverter reference frequency is 30% x 50.00 x 2=30.00Hz
Example 3:
Pulse input frequency is 200Hz (03-27=0.20), duty cycle is 15%, frequency upper limit is 599Hz (00-12=599.00),
and 03-28=500.0. Inverter reference frequency is 15% x 599.00 x 5.00=499.25Hz
Note:
The examples are based on the digital inputs set for NPN input configuration. To use PNP, the relationship
between duty cycle and inverter reference frequency is inverted, so 20% duty cycle translates to 80% inverter
reference frequency.
