Danger
Warning! Possibility of losing control of the car at the end of the run if Drop
Delay and Voltage Decay time exceed Contactor Drop Delay!

Brake - Configuration Tab

Caution
The parameters on this tab are set automati-
cally during brake calibration. Do not modify
these parameters unless advised to do so by
an MCE representative.
• Voltage: The voltage output to the brake coil
at various percentages of maximum voltage,
measured during calibration (see Caution
above).
• Output Timer: The amount of OFF time
during each cycle (delay before turning on
the brake output) required to output the
appropriate voltage to the brake coil at vari-
ous percentages of maximum voltage (see
Caution above).
• Current Reference: The voltage feedback
that represents the brake current at various
percentages of maximum voltage, measured
during calibration (see Caution above).
