 ? The technical performance 
 SQR1 series of intelligent soft starter motor for the exchange of 50Hz, ~ 380 V, 5.5 ~ 500KW various load squirrel cage motors. 
 1, starting mode: 
 a current-limited: to limit the starting current, to reduce the starting voltage, any adjustments, keyboard settings. 
 (b) voltage ramp-type: the motor provides a smooth gradual start-up process, to reduce the impact of the starting current on the grid, reduce vibration and noise of the equipment, to extend the life of mechanical transmission. 
 2, the stop mode: 
 (a) free parking (b) soft stop c. parking brake (ordering agreement) 
 3, the control mode: Input: passive switching signal; 
 4, the system control functions: 
 Intelligence: the control points of all input-output programmable contacts, built-in intelligent program, analyzing a variety of load operating conditions of the drive system; 
 (b) comes with LED display and operation of the keyboard with the machine, set the various parameters and programming; 
 (c) have to lift the remote operation function, in order to ensure the safety of the equipment maintenance personnel; 
 (d) with keyboard control and remote control switching function; 
 (e) and time delay relay, delay relay output contacts 08,10 normally open; 
 (f) Fault output relay, if the system failure relay, downtime reset programmable; 
 (g) self-control bypass contactor output relay when starting the process is complete, the relay; 
 (h) delay start function can be set to 0 ~ 999S delay start and countdown display; 
 i can achieve a soft start to drag more than one motor
