Description
Soft-start devices with brake function are robust electronic control units for soft start-up and braking of three-phase asynchronous machines. The integrated current measurement is used to implement various device protection functions for blocking or heavy starting of the motor. The semiconductors are bridged by means of relays after soft start-up, which ensures low power loss and heating of the device during operation. The device parameters are easily set via potentiometer. Various LEDs indicate the status of the device.
Structure and mode of operation
Two motor phases are influenced by phase control by thyristors in such a way that the currents can increase steadily. The engine torque also acts during ramp-up. This ensures that the drive can start up smoothly and that drive elements cannot be damaged. This property allows for a low-cost design of the drive elements.
Start/stop switch
After starting by pressing the start/stop switch S, the thyristors are bridged by means of internal relay contacts in order to minimize the losses in the device. When the start/stop switch S is switched off, the braking process is activated
initiated. The braking current flows through the stator winding until the motor has been detected, but at the most for a maximum duration of 20 seconds.
· According to IEC/EN 60947-4-2
· 2-phase motor control
· For motor power up to 11 kW at 3 AC 400 V.
· Separate setting options for starting time or starting and braking torque

· With automatic standstill detection
· Current monitoring
To protect the power semiconductors
As device protection for motor blocking
· Wear and maintenance-free
· Auxiliary voltage 24 V DC
· Mains monitoring for phase failure and left rotating field
· Input for recording the motor temperature via PTC (variant /_1_)
· 3 signal relays for status and error messages with LED displays
· Width 112.5 mm
