PARAMETER RANGE DESCRIPTION
Typical Max Speed 500–8000 rpm Set this parameter to the typical maximum motor speed of the vehicle.
Typical_Max_Speed 500–8000 This value does not need to be set precisely; an estimate will do.
All of the vehicle 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 sec to accelerate from
zero to top speed (6000 rpm).
If Max_Speed_SpdM = 3000 rpm, it will take 1.5 sec to accelerate from
zero to top speed (3000 rpm).
If Max_Speed_SpdM = 1000 rpm, it will take 0.5 sec to accelerate from
zero to top speed (1000 rpm).
Swap Encoder Direction On/Off Changes the motor encoder’s effective direction of rotation. The encoder
Swap_Encoder_Direction On/Off provides data used to calculate motor position and speed. This parameter
OptionBits3 [Bit 0] must be set such that when the motor is turning forward, the controller
reports back a positive motor speed.
Positive motor speed must be in the forward direction in order
for the emergency reverse feature to operate properly.
Note: Do not change this parameter while the controller is powering the
motor. Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects
the controller and the operator.
Adjusting this parameter can be hazardous. For instructions,
see Section 5, Step bk (page 78).
Swap Two Phases On/Off If, after Swap Encoder Direction has been set correctly, the vehicle drives
Swap_Two_Phases On/Off in the wrong direction (i.e., drives forward when in reverse, and vice
OptionBits3 [Bit 3] versa), try changing the setting of the Swap Two Phases parameter. This
parameter has the same effect as physically swapping the cables on any
two of the three motor phase connections.
Positive motor speed must be in the forward direction in order
for the emergency reverse feature to operate properly.
Note: Do not change this parameter while the controller is powering the
motor. Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects
the controller and the operator.
Adjusting this parameter can be hazardous. For instructions,
see Section 5, Step bk (page 78).
Encoder Steps 32–256 Sets the number of encoder pulses per revolution. This must be set to
Encoder_Steps 32–256 match the encoder; see motor nameplate.
Note: Do not change this parameter while the controller is powering
the motor. Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects
the controller and the operator.
Adjusting this parameter can be hazardous; setting it improperly
may cause vehicle malfunction, including uncommanded drive. For
instructions, see Section 5, Step
1 (page 76).
