Within the holding time, when CD command (door close command) is given, the drive will begin door close action.

When Pr.04-18 set to 999.9, OD terminal is executing a permanent holding command, user can only terminate this command by using the STOP/RESET key on digital keypad.

This parameter is used to ensure smooth acceleration and deceleration via S-curve, different setting will create different S-curve. When this function is activated, the drive will create a smooth acceleration and deceleration curve by original acceleration and deceleration time. Setting Pr.04-19=0.0 or Pr.04-20=0.0 will create a linear acceleration and deceleration curve.

Actual acceleration time = the selected acceleration time for door open + (Pr.04.19 + Pr.04.20)/2

Door Open DC Brake Current Level

Control mode VF VFPG SVCFactory setting: 0 Settings 0~100%

This parameter sets the level of DC Brake Current output to the motor during start-up and stopping. When setting DC Brake Current, the Rated Current (Pr.00-01) is regarded as 100%. It is recommended to start with a low DC Brake Current Level and then increase until proper holding torque has been attained. Do not set Pr.04-21 greater than rated current in order to prevent motor damage. Also for your personal safety, do not use DC braking for door holding action.

When AC motor drive is in FOCPG/FOCPM control mode, DC brake functions are ready to use, no additional setting is required.
