3 - 15
The Current Level 1 to Decrease to Pr.3-12 after Door Open
Completed
Unit: 0.1
Settings 0.0~150.0% Factory Setting: 50.0
3 - 16
The Current Level 2 to Decrease to Pr.3-12 after Door Open
Completed
Unit: 0.1
Settings 0.0~150.0% Factory Setting: 50.0
The door machine will be in holding torque mode when the motor stall exceeds this setting
after door open complete is reached.
3 - 17 Holding Time for Terminal REV Unit: 0.1
Settings 0.0 to 999.9 sec Factory Setting: 0.0
This parameter is used to remove the REV terminal signal (door open signal) when door open
complete. The AC Motor Drive will still in RUN mode before the setting time. After reaching this
setting, the AC Motor Drive will stop running. This function will be invalid before door open
complete.
The FWD command (door close command) can be operated before this setting to close the
door.
When Pr.3-17 is set to 999.9 (REV terminal is always holding), it needs to stop AC Motor Drive
by
RESET
STOP
key on the keypad.
3 - 18 S Curve Acceleration Time for Door Open Unit: 0.1
Settings 0.0 to 10.0 sec Factory Setting: 0.0
This parameter is used to ensure smooth acceleration and deceleration via S-curve.
The S-curve is disabled when set to 0.0 and enabled when set to 0.1 to 10.0/0.01 to 10.00.
Setting 0.1/0.01 gives the quickest and setting 10.0/10.00 the longest and smoothest S-curve.
The AC motor drive will not follow the Accel Times in Pr.3-07/Pr.3-10
The diagram below shows that the original setting of the Accel/Decel Time is only for reference
when the S-curve is enabled. The actual Accel Time depends on the selected S-curve (0.1 to
10.0).
The total Accel. Time=Pr.3-07 + (2*Pr.3-18) or Pr.3-10 + (2*Pr.3-18)
For example: if Pr.4-05=3, Pr.4-23=2, then the total door close acceleration time =3+(2*2)=7
sec (To calculate with F=60Hz, if F=30, the total acceleration time will be reduced by half)
If Pr.3-18 is larger than Pr.3-07, the total acceleration time=
3-07*3-182*
