PULSE START
level is 80% Un.
Intended to start high friction loads,
requiring high starting torque for a short
time.
A pulse of 80% Un, without Current
Limit, is initiated to break the load free.
Pulse duration is adjustable, 0.1
±
1sec.
After this pulse, the voltage is ramped
down to INITIAL VOLTAGE setting,
before ramping up again to full voltage
according to START PARAMETERS
settings.

This adjustment also determines the
inrush current and mechanical shock. A
setting that is too high may cause high
initial mechanical shock and high inrush
current (even if CURRENT LIMIT is set
low, as the INITIAL VOLTAGE setting
overrides CURRENT LIMIT setting).
A setting that is too low may result in
prolonged time until motor begins to
turn. In general, this setting should
ensure that the motor begins turning
immediately after start signal.
