Controller Overtemp Cutback
1. See Monitor menu » Controller:
Temperature.
2. Controller is performance-limited at
this temperature.
Reduced drive and brake
torque.
Set: Heatsink
temperature exceeded
85°C.
Clear: Bring heatsink
temperature below
85°C.
23
B+ Undervoltage Cutback
1. Normal operation. Fault indicates the
batteries need recharging. Controller is
performance limited at this voltage.
2. Battery parameters are misadjusted.
3. Non-controller system drain on
battery.
4. Battery resistance too high
Reduced drive torque.
Set: Capacitor bank
voltage dropped below
the Undervoltage limit
with the FET bridge
enabled.
Clear: Bring capacitor
voltage above the
Undervoltage limit.
25
+5V Supply Failure
1. Normal operation. Fault shows that
regen
braking currents elevated the battery
voltage
during regen braking. Controller is
None
Set: +5V supply (pin
26) outside the 5
V±10% range.
Clear: Bring voltage
within range.
26
Digital Out 6 Open/Short
1. External load impedance on Digital
Output 6 driver (pin 19) is too low.
Digital Output 6 driver
will
not turn on.
Set: Digital Output
6 (pin 19) current
exceeded 1 Amp.
Clear: Remedy the
overcurrent cause
and cycle power
27
Digital Out 7 Open/Short
1. External load impedance on Digital
Output 7 driver (pin 20) is too low.
Digital Output 7 driver
will
not turn on.
Set: Digital Output
7 (pin 20) current
exceeded 1 Amp.
Clear: Remedy the
overcurrent cause
and cycle power
28
Motor Temp Hot Cutback
1. Motor temperature is at or above the
programmed Temperature Hot setting,
and
the current is being cut back.
2. Motor Temperature Control Menu
parameters are miss-tuned.
Reduced drive torque.
Set: Motor temperature
is at or
above the
Temperature Hot
parameter setting.
Clear: Bring the motor
temperature
within range.
