0h = H free run mode
1h = Small gain
2h = Medium gain
3h = Large gain
(Set to ON mode at power-on.)
0 = H oscillator frequency fixation OFF AFC normal mode
1 = H oscillator frequency fixation ON Oscillator frequency fixed to maximum value
0, 1h = Automatic identification
2h = Forced mode (50Hz)
3h = Forced mode (60Hz)
(Set to OFF mode at power-on.)
0 = Oscillation stop OFF (V DRIVE– and V DRIVE+: normal output)
1 = Oscillation stop ON (V DRIVE– and V DRIVE+: DC output and DC value vary
(Set to automatic selection mode during power-on.)
0 = Non-standard signal mode, standard signal mode and no signal mode
1 = Fixed to non-standard signal mode
