Description:
For high inertia loads that require more braking torque than is available from the D.C.Brake feature, the TMS7 can be configured for 'Soft
Braking'.
In this application the TMS7 is employed with forward run and braking contactors. On receipt of a start signal (pushbutton S1) the TMS7
closes the forward run contactor (K1M) and controls the motor according to the programmed Primary Motor Settings.
On receipt of a stop signal (pushbutton S2) the TMS7 opens the forward run contactor (K1M) and closes the braking contactor (K2M) after a
delay of approximately 2-3 seconds (K1T). K3A is also closed to activate the Secondary Motor Settings which should be user programmed
for the desired stopping performance characteristics.
When motor speed approaches zero the shaft rotation sensor (A2) stops the soft starter and opens the braking contactor (K2M).
Function Settings:
-
Function 23. Relay Output C Functionality = 0 (Assigns the Trip function to Relay Output C)
-
Functions 1~9 (Sets starting performance characteristics)
-
Functions 80~88 (Sets braking performance characteristics)
