Calculating Motor’s Torque
Motor torque with soft starter
M soft = ( U soft / U n) 2
* M start
Assuming M start = 1.8 * M n
Assuming U start =0.5 Un M=(0.50)2
M soft = (0.25) * 1.8 = 0.45 M start
Torque is reduced by the square of the voltage reduction

Pump Stopping – D.O.L
 When motor starter (DOL) is
opened, abruptly stopping the
pump, speed and flow are
quickly reduced. This may
cause a Water Hammer

noise with severe damage to
pipes, joints, fittings, valves,
etc. )DOL opens

54. SOLCON
Pump Stopping - Soft Starter (standard)
 When using a standard soft
starter, while pumping to a
higher elevation, motor
torque may quickly fall
below load torque (as torque
decreases at the square route
of voltage reduction). This
may cause abrupt stalling
instead of smoothly
decreasing speed to zero,
creating the Water Hammer
phenomenon.

Starting from a Diesel-Generator
When starting from older D.G. sets (especially those equipped with low
cost Voltage Regulators) both voltage and frequency are unstable, causing
irregular thyristor firing. The HRVS-DN is equipped with a special
program overcoming the voltage and frequency instability.
Two options to operate Generator Mode:
 Use Basic Curve.
 set Dip Switch 3 to On and energize the Dual Adjustment Terminal.
When testing in Generator mode at low voltage, motor must be loaded.
When motor can operate from Mains and D.G (stand-by D.G) set
Dip Switch # 3 to On. However, Dual Adjustment Terminal should be
energized only when D.G. is running.
