Synchronization

Description
You can synchronize a motor with the line supply using the "Synchronization" function and
an existing voltage sensing module VSM10 (to measure the line voltage). 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.
Use of the bypass function supports temporary (for example, for maintenance work without
plant standstill) or permanent operation of the motor on the line supply.
Synchronization is activated with parameter p3800. A VSM10 which is assigned to a drive
(via DRIVE-CLiQ), measures the line supply voltage.
Requirement
● Drive in the vector control mode with Voltage Sensing Module (VSM10)
● Induction motor without encoder
● Vector control
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 (p3802)
