The five Checks Enable parameters are used to enable driver and coil fault
On / Off
detection at the five individual drivers (at Pins J1-6, J1-5, J1-4, J1-3, and J1-
2). When a Driver Checks parameter is enabled, the associated driver, driver
wiring, and driver load are checked to verify that the driver correctly drives the
On / Off
load both high and low. The checks will occur regardless of the PWM output
On / Off
of the driver. The checks will detect both open and shorted conditions. When a
fault is detected, the controller opens the driver and issues a fault code.
If nothing is connected to a driver, its Checks Enable parameter should be set
On / Off Off.
On / Off NOTE: Short circuit protection is always active at these five drivers, regardless
of how Checks Enable is set.
On / Off
On / Off
0 – 200 mA Sets the upper threshold of the combined current of the 5V and 12V external
supplies. At or above this threshold a fault will be created that can be read by
0 – 800
VCL.
0 – 200 mA Sets the lower threshold of the combined current of the 5V and 12V external
supplies. At or below this threshold a fault will be created that can be read by
0 – 800
VCL.
DRIVERS: PWM FREQUENCY PARAMETER
ALLOWABLE RANGE
100 – 1000 Hz This single parameter defines the frequency of Drivers 1 through 4.
100 – 1000
MOTOR MENU
ALLOWABLE RANGE
500 – 8000 rpm Set this parameter to the typical maximum motor speed of the vehicle. This
value does not need to be set precisely; an estimate will do. All of the vehicle
500 – 8000
response rates are normalized to Typical Max Speed.
For example, suppose Typical_Max_Speed is fixed at 6000 rpm, and
Full_Accel_Rate_LS_SpdM = 3.0 seconds:
If Max_Speed_SpdM = 6000 rpm, it will take 3.0 seconds to accelerate from
zero to top speed (6000 rpm).
If Max_Speed_SpdM = 3000 rpm, it will take 1.5 seconds to accelerate from
zero to top speed (3000 rpm).
If Max_Speed_SpdM = 1000 rpm, it will take 0.5 seconds to accelerate to
accelerate from zero to top speed (1000 rpm)
