Chapter 4 Parameter SettingsDD Series

1.Incorrect door close limit:

a.The signal for the door open limit is received before Pr.05-04 setting.

b.The signal for the door open limit isn’t received after Pr.05-06setting.

2.Incorrect door open limit:

a.The signal for the door close limit is received before Pr.04-04 setting.

b.The signal for the door close limit isn’t received after Pr.04-06 setting.

When bit 1=1, the drive will not re-open the door when it detects a door closing torque higher than Pr.05-25 (05-28).

When bit 3=1 and the drive is in torque holding status after door open completely, the door width is auto-reset to 100.0%.

Position Control Mode

Control mode VF VFPG SVC FOCPG FOCPM

Factory setting: 0

Settings 0: No limit signal, detect by PG number and current level.

 

1:Door open limit signal only, door close by PG number or current level detection.

2:Door close limit signal onlydoor open by PG number or current level detection.

3:Door open and close limit signal

4:Detect by PG number and also accept external door open/close limit signal

5:No limit signal, detect by PG number and current level. (For Pr.00-09=3 speed control mode)

When Pr.06-11 setting is 1 to 5 and Pr. 06-12 is NOT set to 0, the AC drive will regard this setting as open/close complete position if following two conditions are met:

A. It has open/close limit signal.

B. When the stall current level exceeds Pr.06-12.

When this parameter is set to 0 “No limit signal”, the door open/close complete position can be check by following two methods:.

A. When Pr. 06-12 is set to 0: When PG feedback frequency is almost 0 due to motor stall, it is regarded as open/close complete position.

B. When Pr. 06-12 is NOT set to 0: When current exceeds this level due to motor stall, it is regarded as open/close complete position.

NOTE

1.It is recommended to use method B for the transmission mechanism skids easily.

2.This function works in distance control mode only. For multi-step control mode, please use door open/close limit signal to verify if door reaches its open/close complete position.

Stall Current Level of Position Mode

Control mode VF VFPG SVC FOCPG FOCPM

Factory setting: 30.0

 

Settings 0.0~200.0% (AC drive’s rated current)

 

This parameter sets the stall current level for open/close complete position and is to be used with Pr.06-11.

Door Open/Close Holding Time Before Next Demo

Control mode VF VFPG SVC FOCPG FOCPM

Factory setting: 2.0

 

Settings 0.0~99.99sec

 

During demonstration in demo mode, this parameter sets the door holding time before it goes on to the next demonstration.
