(*) The acceleration time shown is the time from 0 Hz to 100 Hz. This is the ideal ramp
calculated by the software; the real ramp could change as a function of motor control
parameter setting and, obviously, as a function of the load.
(**) The braking feature is based upon deceleration ramps. The value shown in the table
is the time to decrease the speed from 100 Hz to 0 Hz. This is the ideal ramps calcu-
lated by the software; the real ramp could change as a function of motor control pa-
rameter setting and, obviously, as a function of the load.
5.5.4 "Dualac2&hp" - Slave
Here following the list of parameters which can be set in this menu:
1 PU. ACCELER. DELAY: acceleration ramp of pump motor.
2 PU. DECELER. DELAY: deceleration ramp of pump motor.
3 SPEED LIMIT: determines the maximum lifting speed (per cent of
voltage applied to the motor) with a potentiometer
control, when the potentiometer is at the maximum of
the programmed range.
4 CREEP SPEED: determines the minimum lifting speed (per cent of
voltage applied to the motor) with a potentiometer
control, when the potentiometer is at the minimum of
the programmed range.
