OPTION
LS-I1 provides for : Current limit during ramp-up
with switch-on pulse, monitoring of power with
overload trip (stall protection) power factor
improvement at low load special circuit to damp
drive oscillation (e.g. with pumps) energy saving
circuit for lightly loaded drives |
|
OPTION
LS-I2 provides for : Current limit during ramp-up
start monitoring, optimised operation with pumps |
|
OPTION
LS-N provides for : Closed-loop speed control for
load-independent starting, operation for pumps |
