Installation
1-26 Manual # 42-02-2P26
• Overcurrent: Overcurrent limit specification for the brake board is set at 10 A. If brake coil
current exceeds this amount, the BRK FLT LED will light and the driver will be disabled
until the brake is dropped again.
• IGBT: If the Q4 IGBT fails shorted, the IGBT FLT LED will light and will not go out until
the board is repaired. If the board is powered OFF, then ON the IGBT FLT LED will imme-
diately light again.
• If brake pick/position switch is installed (Config 01 > Spare Inputs > Brake Sw), user may
see brake pick switch open/closed/flaky faults if switch malfunctions.
Brake Transformer Information Now that the brake is picking and holding, it is
time to do a rough calibration of inspection speed. Using a hand tachometer, adjust drive
parameter A1 CONTRACT MTR SPD until the car velocity matches the setting under CONFIG
02/SYSTEM CONTROL PARAMETERS/INSPECTION SPEED. Increasing the drive parameter
will result in a faster moving car.
Please refer to the SCE-BRK description in Section 2 of this manual for brake transformer infor-
mation, page 2-37.
Initial Speed Calibration
Now that the brake is picking and holding, it is time to do a rough calibration of inspection
speed.
Magnetek
On Inspection Mode: Using a hand held tachometer, adjust drive parameter A1 CONTRACT
MTR SPD until the car velocity matches the setting under CONFIG 02 > SYSTEM CONTROL
PARAMETERS > INSPECTION SPEED. Increasing the drive parameter will result in a faster
moving car.
TORQMAX
On Inspection Mode: Using a hand held tachometer, adjust Machine Data Parameters > LN02
GEAR REDUCTION RATIO until the car velocity matches the setting under CONFIG 02 > SYS-
TEM CONTROL PARAMETERS > INSPECTION SPEED. Increasing the drive parameter will
result in a faster moving car.
