
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


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


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
