9.3.19 Synchronization
Description
The "Synchronization" function and an existing VSM10 Voltage Sensing Module (to measure
the line voltage) synchronizes a motor to the line supply. The connection to the line supply or
the required contactor control can be realized using the existing bypass function or a higher-
level control system.
The use of the bypass function permits the temporary (e.g. to perform maintenance work
without system standstill) or permanent operation of the motor on the line supply.
The p3800 parameter activates the synchronization. The voltage is acquired via a VSM10
assigned to the drive (via DRIVE-CLiQ) and measures the line supply voltage.
Features
● Connector inputs for the actual voltage sensing of the motor via VSM10 (p3661, r3662)
● Setting a phase difference (p3809)
● Can be activated by parameter (p3800)
● Enable via parameter (p3802)
