4 Further Status Information
The status information, 2.10 Accelerator Slip Demand, also relays some operational status data about the controller. This is in the
form of a two-letter abbreviation that replaces the “Hz” on the Programmer’s screen. These abbreviations are listed below.
N: Neutral, i.e. no drive demand and controller is not pulsing.
FD: Forward Drive, i.e. controller is applying forward drive to the motor.
FL: Forward Drive Left controller in dual motor configuration.
FR: Forward Drive Right controller in dual motor configuration.
RD: Reverse Drive, i.e. controller is applying reverse drive to the motor.
RL: Reverse Drive Left controller in dual motor configuration.
RR: Reverse Drive Right controller in dual motor configuration.
DB: Direction Braking, i.e. the controller is braking as the result of a direction change.
NB: Neutral Braking, i.e. the controller is braking as a result of a neutral drive demand.
FB: Footbraking, i.e. the controller is braking as a result of the Footbrake being operated.
HH: Hill hold i.e. the controller is holding the vehicle stationary on a hill.
HF: Restrained hill hold in the forward direction, i.e. the controller is limiting the roll-away speed of the vehicle.
HR: Restrained hill hold in the reverse direction, i.e. the controller is limiting the roll-away speed of the vehicle.
SB: Standby, i.e. the controller is in a standby condition.
The status information, 2.11 Damped Slip Demand, also relays some status data about the controller. Again, this is in the form of
a two-letter abbreviation that replaces the “Hz” on the Programmer’s screen. These abbreviations are listed below.
SM: Maximum Speed, i.e. maximum speed is available, no limits or interlocks active.
S1: Speed Limit 1 is active.
S2: Speed Limit 2 is active.
S3: Speed Limit 3 is active.
S4: Not used.
S5: Not used.
S6: Not used.
SI: Inching Speed is being applied.
SB: BDI Speed Limit is being applied.
SD: Dual Motor Speed Limit is being applied.
CL: Current Limit, i.e. the controller is in drive current limit mode.
BL: Brake Current Limit, i.e. the controller is in braking current limit mode.
CT: Controller Temperature, i.e. the controller has reduced its output due to a high heatsink temperature.
MT: Motor Temperature, i.e. the controller has reduced its output due to a high motor temperature.
The status information 2.12 Motor Voltage, also relays the current error code. This is in the form of an abbreviation as shown
below.
Fxx: Error Code, where ‘xx’ denotes the specific error.
