N700E INSTRUCTION MANUAL
3-41
b34
Maximum OVS Output Frequency
Range: 0.0 ~ 300.0 Hz in 0.1 Hz
Real time editable a maximum frequency limit for OVS function
Related Parameters:
b35
OVS P Gain
Range: 0 ~ 10,000 in 1
Real time editable P gain for OVS PID loop
PIOut = err * Kp
Hz = err(%) * Kp * scalefactor(50 * 1e-6)
Example
err 10%, Kp = 1000
PIOut = 0.5Hz
Recommended Value in test bench
1000 or less than 5000
Related Parameters
b36
OVS I Gain Time
Range: 0 ~ 10,000 Sec in 1 Sec
Real time editable I gain for OVS PID loop
PIOut = ∫(err * Ki)
Hz += err(%) * Ki * scalefactor(50 *1e-6), dT = 1msec
Example ( Integration Time to 10Hz on Error)
err 10%, Ki = 1000
Time to 10Hz on 10% Error = 20msec
err 10%, Ki = 100
Time to 10Hz on 10% Error = 200msec
err 10%, Ki = 10
Time to 10Hz on 10% Error = 2000msec
Recommended Value in test bench
100 or less than 500
Related Parameters:
b37
OVS D Gain Time
Range: 0 ~ 10,000 Sec in 1 Sec
Real time editable D gain for OVS PID loop. Its value depends on b39; filter bandwidth.
Thus, if b39 is not changed, no need to change OVS PID D Gain value. Most application,
this value should not be set over 3000
Recommended Value as a function of b39
If b39 < 10
b37: 0 ~ 500
If b39 < 30
b37: 500 ~ 1000
If b39 < 50
b37: 1000 ~ 1500
