MCE SmarTRAQ - Adjusting Drive Parameters

Adjusting Parameters
All door operator adjustments are made by selecting and changing parameters using inverter
drive programmer switches. All parameter values are numeric, from 0 to 31. The higher the
number, the greater the parameters effect.
Note
Parameter values can only be changed or viewed when elevator doors are Full Closed and Door
Close Limit LED is lighted.
After changing parameters, you must select the parameter “do” and press Enter to
save the changes. If you change a torque value (marked with an * in the table), you
must perform a door learn operation after saving changes. To return to automatic
door operation, place the Local/Remote switch back in Remote position. (Otherwise, the opera-
tor will not respond to open or close commands from the elevator controller.)
Use the following table and the Motion Profile illustration to adjust parameters.
Table 4. Inverter Drive Parameters
Parameter Description
PL Start Open Position: Position where doors start to accelerate. Higher value = Position farther
from full close.
P2 Open Slowdown Position: Position where doors begin to decelerate from high to low opening
speed. Higher value = deceleration nearer to full open position.
P7 Close Slowdown Position: Position where doors begin to decelerate from high to low closing
speed. Higher value = deceleration nearer to full close position.
Po Reopen Slowdown Position: Higher value = Reopen slowdown position starts nearer to full
open.
Pc Reclose Slowdown Position: Higher value = Reclose slowdown position starts nearer full
close.
Pr Reopen Distance: Distance from full open where Po parameter, Reopen Slowdown Position,
and Ar parameter, Reopen Deceleration, can be activated. 00 value = from full open to 75%
of full open. Setting parameter from 01 to 31 = from 75% of full open to 25% of full open.
Note: Most door operators will not require adjustment of this parameter. This parameter is
factory set to 00. Should be set to 00 unless absolutely necessary. See Caution following this
table.
U0 Start Open Speed: Higher value = More speed.
U1 High Opening Speed: Higher value = More speed.
U2 Low Opening Speed: Higher value = More speed.
U3 High Closing Speed: Higher value = More speed.
U4 Low Closing Speed: Higher value = More speed.
Ud Nudging Speed: Higher value = More speed.
A0 Opening Acceleration: Higher value = Faster acceleration.
A1 Opening Deceleration: Higher value = Faster deceleration.
A2 Closing Acceleration: Higher value = Faster acceleration.
A3 Closing Deceleration: Higher value = Faster deceleration.
Ab Braking Deceleration: Deceleration during door reversal. Higher value = More deceleration.
Ar Reopen Deceleration: Higher value = Faster deceleration.
F3 Heavy Door High Closing Speed: Higher value = More speed. This value must be lower than
U3.
F7 Heavy Door Close Slowdown Position: Position where doors begin to decelerate from high to
low closing speed. Higher value = deceleration nearer to full close position.
Fd Heavy Door Nudging Speed: Higher values = More Speed.
