Description
HW EXTENSION
(A)
ABSENT,
PRESENT
This parameter defines the controller version.
ABSENT = ACE3 standard version.
PRESENT = ACE3 premium version.
PWM AT LOW FREQ
(A)
(Factory adjusted). 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)
(Factory adjusted). 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)
(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”.
NOTE: only Zapi technicians can change this value through a special
procedure.
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. Reserved.
NOTE: only Zapi technicians can change this value.
CAN BUS SPEED
(A)
20 kbps ÷ 500
kbps
This parameter defines the CAN bus data-rate in kbps.
The available values are:
20, 50, 125, 250, 500
EXTENDED FORMAT
(A)
OFF, ON This parameter defines the CAN bus protocol.
ON = standard format (11 bit);
OFF = extended format (29bit).
DEBUG
CANMESSAGE
(A)
OFF, ON This parameter enables or disables special debug messages. Reserved.
CONTROLLER TYPE
(A)
0 ÷ 9 This parameter defines the controller type. Reserved.
NOTE: only Zapi technicians can change this value.
