2.9 n: Special Adjustments
• If the Synchronous Transfer command input is active, the following detections will be disabled: momentary power loss
ride-thru, fault restart function, phase loss detection, and ground fault detection.
n7-51: Synchronous Transfer Mode
n
Selects if the Synchronous Transfer is enabled.
No.
n7-51 Synchronous Transfer Mode
Setting 0: Disabled
The Synchronous Transfer will not operate.
Setting 1: Enabled
Use this setting if the Synchronous Transfer is used.
Before this setting is enabled, assign the Synchronous Transfer to the multi-function contact inputs and multi-function
contact outputs. If there are any assignment errors with the multi-function contacts, an operation error (OPE20) will
occur.
n7-52: Amplitude Synchronous P Gain
n
Sets the proportional gain of the control that synchronizes the amplitudes of the commercial power supply voltage and
the drive output voltage.
If Synchronous Transfer control is in effect and the drive output voltage oscillates, decrease the setting.
No.
n7-52 Amplitude Synchronous P Gain
n7-53: Amplitude Synchronous I Time
n
Sets the integral time of the control that synchronizes the amplitudes of the commercial power supply voltage and the
drive output voltage.
If Synchronous Transfer control is in effect and the drive output voltage oscillates, increase the setting.
No.
n7-53 Amplitude Synchronous I Time
n7-54: Amplitude Synchronous Primary Delay Time Constant
n
Sets the primary delay filter of the control that synchronizes the amplitudes of the commercial power supply voltage and
the drive output voltage.
If Synchronous Transfer control is in effect and the drive output voltage oscillates, increase the setting.
No.
n7-54 Amplitude Synchronous Primary Delay Time Constant
n7-55: Amplitude Synchronous Output Limit
n
Sets the output limit of the control that synchronizes the amplitudes of the commercial power supply voltage and the
drive output voltage. Set as a percentage of the voltage class.
No.
n7-55 Amplitude Synchronous Output Limit
