4.3.1 AI Zero Drift Auto Correction
Step Function Code Setting Parameter Description Remarks
1. Set the command
source.
F0-02 = 0
The operation panel control
mode is used.
The LOCAL/REMOT indicator is OFF.
2. Perform AI zero drift
auto correction.
A3-20 = 1
The AI zero drift auto
correction function is enabled.
After the operation panel displays
"Alcod", press
RUN
. Then, AI zero
drift auto correction is carried out.
Note
•
You can also perform AI zero drift correction manually: When A3-20= 0 (that is, AI zero drift auto
correction is disabled), view the values of three AIs in U1-04 to U1-06, add 10 mA to each of the values
and then enter the results in F4-18, F4-23, and F4-28.
•
After AI zero drift auto correction is completed, the value of A3-20 is automatically restored to 0.
4.3.2 Selection and Parameter Setting of Hydraulic Control Mode
Hydraulic Mode Selection Function Code Setting Description
Non-oil pressure control
mode
A3-00 = 0 The speed mode is used.
Oil pressure control mode 1 A3-00 = 1
The host computer provides the oil pressure reference and ow
reference by using CAN communication; AI3 provides the oil
pressure feedback; the servo drive conducts hydraulic control.
Oil pressure control mode 2 A3-00 = 2
AI1 provides the oil pressure reference; AI2 provides ow
reference; AI3 provides the oil pressure feedback; the servo
drive conducts oil pressure control.
CAN oil pressure control
mode (specialized)
A3-00 = 3
It is the oil pressure control mode implemented by using CAN
communication with the host computer. The servo pump control
parameters in group A3 are invalid.
Reserved A3-00 = 4 Reserved
When the non-oil pressure control mode (A3-00 = 0) is switched over to the oil pressure control mode (A3-00 ≠ 0),
the related parameters are set automatically, as listed in the following table.
Function Code Parameter Name Setting
F0-01 Control mode 1: Closed-loop vector control (CLVC)
F0-02 Command source selection 1: Terminal
F0-03 Main frequency source X selection
If A3-00 = 2, set F0-03 to 3 (AI2). If A3-00 = 1 or 3, set
F0-03 to 9 (Communication).
F0-17 Acceleration time1 0.0s
F0-18 Deceleration time1 0.0s
F1-00 Motor type 2: PMSM
