PARAMETER RANGE DESCRIPTION
Brake Pedal Enable On/Off Determines whether the brake input and algorithm are enabled, making
Brake_Pedal_Enable On/Off the brake throttle part of the motor control command.
OptionBits1 [Bit 3]
Brake Type 1–5 The 1234/36/38 controllers accept a variety of brake inputs. The brake type
Brake_Type 1–5 parameter can be programmed as follows:
1 2-wire rheostat, 5kΩ–0 input
2 single-ended 3-wire 1kΩ–10kΩ potentiometer,
0–5V voltage source, or current source
3 2-wire rheostat, 0–5kΩ input
4 (not applicable)
5 VCL input (VCL_Brake)
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.
Brake Deadband 0–5.00 V
Brake_Deadband 0–32767
Brake Map 0–100 %
Brake_Map 0–32767
Brake Max 0–5.00 V
Brake_Max 0–32767
Brake Offset 0–100 %
Brake_Offset 0–32767
VCL Brake Enable On/Off When programmed On, the brake processing with fault detection will
VCL_Brake_Enable On/Off operate normally; however, the brake command (see Figure 14) will require
VCL_Brake_Enable_Bit0 [Bit 0] VCL to define the connection between the OS_Brake and VCL_Brake
variables. This allows VCL flexibility and customization of throttle processing,
while still allowing Brake_Type 1–3 with brake fault detection.
The four Brake throttle adjustment parameters are the same as
their Drive throttle counterparts; see descriptions and Figure 13.
