Determines whether the brake input and algorithm are enabled, making the
brake throttle part of the motor control command.

These E and SE controllers accept a variety of brake inputs. The brake type
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
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.

The four Brake throttle adjustment parameters are the same as their
Drive throttle counterparts; see descriptions and Figure 17.

Sets the low pass lter cutoff frequency for the pot2 wiper input. Higher
values will make the brake more responsive to quick changes. Lower values
will make the brake less responsive to electrical noise.

When programmed On, the brake processing with fault detection will
operate normally; however, the brake command will require VCL to dene
the connection between the OS_Brake and VCL_Brake variables. This allows
VCL exibility and customization of throttle processing, while still allowing
Brake_Type 1–3 with brake fault detection. Figure 18 (page 112) illustrates
these brake chains.
