SmarTraq
10 Manual # 42-02-D008 Rev. A2
Motor Terminal Designation
The motor has six terminals, but only four are used. Looking down at the motor from above
with the shaft facing you: Starting on the left side closest to the shaft, the first terminal is “W”,
then “V” in the middle, and “U” toward the encoder end. The middle terminal on the right side
is “N.”
Learn Operation
The “learn operation” can only take place if the drive thinks the doors are fully closed (indicated
when “Lr” is displayed and the DCL LED is lighted). Hold Open/Close switch in close direction
until “Lr” is displayed and the DCL LED is lighted. Reduce “C1” parameter if torque is too high
in open direction. See table and adjust closing torque parameters if torque is too high in close
direction.
Stall Protection
SmarTraq has built-in stall protection in both directions of travel. In the open direction, an
internal stall timer is set for approximately one minute. If the door open signal to the drive is
activated for more than one minute, the drive will automatically shut off. The drive will not
respond until the signal is removed and reapplied or the opposite direction signal is applied.
The stall timer for the close direction operates in a similar manner, but is set for approximately
two minutes.
Door Open and Door Close Protection Timers
Door open and door close protection timers must be set longer than it takes the doors to open or
close at the lowest speeds (first open operation after restoring power and nudging close). Door
open and close protection timers are set at the elevator Controller.
Temporary Operation for Evaluation
Temporary operation for evaluation can be accomplished easily by removing the existing motor
and setting it aside without removing the wires. Rest the drive on the car top. Install the new
motor and wire the motor and encoder to the drive. Wire the drive to a power cord with a plug.
(Be certain that the outlet is providing the correct 120, 208, or 240VAC operating
power and that the inverter drive input wiring has been properly set for that volt-
age.) Plug the power cord into the car top electrical outlet. Turn on power and adjust the door
operator. Once you’re satisfied that everything is OK, either return the door operator to its orig-
inal condition or remove the old motor and temporary wiring, mount the drive, wire the new
motor and encoder to the drive and wire the drive to the controller.
MCE does NOT recommend permanently wiring the drive to the car lighting power circuit.
