1. Scope of Application
This article is relevant for debugging and configuring ZAPI-COMBIX
Drives.
Second, Debugging Resources
- Tools for Debugging:
Debugging through the handheld side of the ZAPI drive.
For connection and debugging methods, please refer to the Smart Console User Guide - Easy Operation Version (Chinese) V0.0.pdf
Step Three: Wiring and Parameter Modification
3.1 Electrical Connection
Connect the driver cables in accordance with the electrical diagram of the vehicle.
Notice:
- The electrical wiring diagram for the same driver may vary for different forklifts. Therefore, refer to the actual electrical schematic diagram for accurate information.
3.2 Parameter Modification Procedure
- Connection
Smart Console
Hand End
Connect the handheld end to the ZAPI
and note the distinction between CANH
and CANL
above the drive when using the smart Console
.
- Modify the parameters based on Step 4: Drive Configuration Parameters.
3.3 Attention Items
Note:
- When connecting to the
smart Console
, always check the connections forCANH
,CANL
, andF2A
to ensure they are correct. - Make sure to select the correct baud rate for the connection.
Four, Drive Configuration
4.1 Modification of ZAPI driver kinematic parameters
Issue: The vehicle is unable to move when in normal condition and at normal speed. Upon inspection, the speed sent by the SRC controller is normal and the ZAPI driver has driving current output, but the motor remains in a state of blocked rotation.
Parameter location in menu:MAIN MENU
- HARDWARE SETTING
Parameter modification:
- Change the
SAT FREQUENCY
to 160HZ; - Change the
BRAKING MODUL
to 150HZ; - Adjust
BOOST AT HI FREQ
to 63%; - Set
BOOST CORNER FRE
to 60; - Set
MAXSLIP 0
to 4; - Set
MAXSLIP 1
to 9; - Set
FREQSLIP 1
to 25; - Set
MAXSLIP 2
to 8; - Set
FREQSLIP 2
to 45; - Set
MAXSLIP 3
to 8; - Set
FREQSLIP 3
to 50; - Set
MAXSLIP 4
to 10; - Set
FREQSLIP 4
to 55;
Notice:
- Modify the parameters on the left side of the parameter list to match the parameters in the red box on the right. This will resolve the issue of motor rotation being blocked due to low speed torque.
- If the ZAPI driver is still outputting drive current but the motor remains locked, adjust the parameters as described above.
4.2 ZAPI Driver Proportional Valve Parameters Modified
Addressing issues during the descent process, such as fork jitter and unstable control speed of the proportional valve, parameters were adjusted based on existing analysis. However, after adjusting these parameters, the issue of the control proportional valve not responding well to delivery speed remained unresolved.
The parameter can be found in the following menu location: MAIN MENU
- SPECIAL ADJUSTMENTS
- Change the value of
MINEVP
to 6.3; - Change the value of
MAXEVP
to 70.2; - Set the value of
EVP OPEN DELAY
to 0; - Set the value of
EVP SHUT DOWN DELAY
to 0; - The
DITHER AMPLITUDE
[high-frequency oscillation amplitude] should be set to 0; - The
DITHER FREQENCY
[high-frequency oscillation frequency] should be set to 83.3. If jitter occurs, change this value to 41.6;
