u n7: Synchronous Transfer with a Commercial Power Supply (Available from the
Drive Software Versions S0103 and Later.)
The Synchronous Transfer cannot be used when A1-02 is set to 2 (Open Loop Vector Control).
System Configuration
n
Figure 2.81
shows the system configuration for Synchronous Transfer.
To perform a Synchronous Transfer, the following devices and interface must be connected in addition to the standard
connections for the drive.
External sequence circuits for Synchronous Transfer are also required.
• Inside drive
• Drive/external sequence circuits
• Drive/motor
• Commercial power supply/motor
• Drive/breaker
<1> The breaker command requires a separate relay that satisfies the specifications of the breaker to be used.
