Handling Method:
The upper and lower voltage limits of the accelerator are not collected. Enter the
PROGRAM VACC menu and collect again. Accelerator voltage collection steps:
1) Open ZAPI CAN CONSOLE → FUNCTION → program VACC → click acquire
2) Rotate the handle and a value appears. Save, restart the key.
Refer to the 2.3 Accelerator Voltage Collection and Debugging Steps in Chapter 2 of the
ZAPI Controller Tutorial for details.
3) Accelerator error. The accelerator pedal may not return, or the accelerator internal
error.
4) Check whether the accelerator cable is properly connected;
5) If a fault cannot be eliminated, the controller shall be replaced.
58. Error ID: 02A86
Error Description: POS. EB. SHORTED
Cause A
When the interlock is not closed down, the high-end driver of the electromagnetic brake
outputs high voltage.
Handling Method:
1) Check whether there is a short circuit or low impedance pulling down the output
between B1 and B5.
2) If the high-end outlet of the electromagnetic brake is not connected, this high
voltage still exists and the driving circuit inside the controller has been broken;
Pin B1 outputs the positive power supply of the brake coil (equal to B+).
The driver of the brake coil B5 output; PWM control; 2.5A maximum consistent current
(drive to B-).
B1 is internally installed the freewheeling diode.
56. Error ID: 02A84
Error Description: CAN BUS KO BMS
Cause A
BMS communication failure.
Handling Method:
Check whether the BMS communication circuit is normal.
57. Error ID: 02A85
Error Description: VACC OUT RANGE
Cause A
Detection time: standby mode.
The alarm displays that the voltage of the accelerator is at least 1V higher than the
minimum value set in the accelerator signal(PROGRAM VACC).
