SMS-Hstart
SMS-Hstart is able to limit both the inrush current absorbed from the network and the
mechanical torque transferred to the load. During start-up, there is a gradual increase in the
voltage and torque supplied to the motor with constant monitoring of current consumption.
Starting of the motor takes place following closure of the external run contact (terminals 1-2)
SMS-Hstart starts the motor by initially providing the starting torque set by the TORQ trimmer
and increasing it up to the maximum torque, in the time set by the ACC trimmer.
SMS-Hstart switches off on opening of the run command.
During the start-up phase, the output current is monitored. On reaching the current limit, set by
the IMAX trimmer, the acceleration ramp is "slowed down", allowing the motor to rev without
using additional power.
