SPECIAL ADJUST.
Parameter Allowable range Description
ADJUSTMENT #03
(Read Only)
0% ÷ 255% Gain of the pump-motor current-sensing amplifier.
NOTE: only Zapi technicians can change this value through
a special procedure.
SET CURRENT PUMP
(Read Only)
See table on the right This is the pump motor maximum current.
Controller
voltage
Allowable values
[Arms]
24V 270, 300, 400
36V/48V 220, 300
80V 200
PWM AT LOW FREQ
(A)
This parameter defines the power-bridge PWM frequency at
low speed.
NOTE: only Zapi technicians can change this value through
a special procedure.
PWM AT HIGH FREQ
(A)
This parameter defines the power-bridge PWM frequency at
high speed.
NOTE: only Zapi technicians can change this value through
a special procedure.
FREQ TO SWITCH
(A)
Volt (Factory adjusted). This parameter defines the electrical
frequency at which the switching frequency is changed from
PWM AT LOW FREQ to PWM AT HIGH FREQ.
DITHER AMPLITUDE
(A)
0% ÷ 13% This parameter defines the dither signal amplitude. The
dither signal is a square wave added to the proportional-
valve set-point. In this way the response to set-point
variations results optimized. This parameter is a
percentage of the valve maximum current. Setting the
parameter to 0% means the dither is not used.
The available values are:
0.0%, 1.0%, 2.5%, 4.0%, 5.5%, 7.0%, 8.5%, 10%,
11.5%, 13.0%
DITHER FREQUENCY
(A)
20.8 Hz ÷ 83.3 Hz This parameter defines the dither frequency.
The available values are:
20.8, 22.7, 25, 27.7, 31.2, 35.7, 41.6, 50, 62.5, 83.3
HIGH ADDRESS
(A)
0 ÷ 4 This parameter is used to access special memory
addresses.
CAN BUS SPEED
(A)
20 kbps ÷ 500 kbps This parameter defines the CAN bus data-rate in kbps.
20, 50, 125, 250, 500
EXTENDED FORMAT
(A)
OFF, ON This parameter defines the CAN bus protocol.
DEBUG CANMESSAGE
(A)
OFF, ON This parameter enables or disables special debug
messages.
