Not used.
Battery voltage 'becoming' too low. Charge battery or check its condition and connections.
2
3
Pump Inhibit Active. Check Connector A pin 7 status.
Battery voltage 'becoming' too high. Reduce braking levels or pump speed.
4
5
Thermal foldback. Allow motor to cool, operate application within specification.
6
Controller over-temperature. Allow controller to cool and check drive train.
7
Out-of-Range programming. Check all parameters are within permitted limits.
8
Default settings restored after re-flash. Cycle power.
9
Internal memory error. Contact Service Agent.
10
Not used.
11
Not used.
12
Pump input switches are active or pump potentiometer > 0.5% at start-up. Check switches
and pump potentiometer.
13
Not used.
14
Not used.
15
Internal 12 V supply too low. Check peripherals and battery.
16
Not used.
17
Battery voltage too low. Charge battery or check its condition and connections.
18
High-side MOSFET error in neutral or while pulsing. Check motor insulation and line
contactor. If error persists, contact Service Agent.
19
Low-side MOSFET error while pulsing. Check motor insulation. If error persists, contact
Service Agent.
20
Motor over-current. Check programming of motor parameters.
21
Contactor coil error. Check contactor coil(s) and connections.
22
Battery voltage too high. Reduce braking levels or pump speed.
23
Low-side MOSFET error in neutral. Check motor insulation and line contactor. If error
persists, contact Service Agent.
24
Controller error or line contactor coil error. Check line contactor coil. If error persists,
contact Service Agent.
25
Contactor error. Check coil(s) & contacts.
26
Controller error. Contact Service Agent.
27
Low-side MOSFET error before line contactor has closed. Check motor insulation and line
contactor. If error persists, contact Service Agent.
28
Not used.
29
CAN error. A CAN node is not responding. Check all nodes and their connections.
30
Over-speed or encoder error. Check encoder programming value 4.3 Number of Teeth is
correct and ensure that 4.8 Motor Speed Maximum is higher than 1.4 Speed 1.
