User Manual of EM730 Series Inverter F27.22, wire disconnection will not be detected. Tens place of F27.20 = 1: no detection Wire disconnection will not be detected. Hundreds place of F27.20 = 0: Protection terminal action only In case of wire disconnection, the inverter will continue to run at the set frequency of F27.24, and only the 68# function terminal and protection output terminal will act. Hundreds place of F27.20 = 1: Delayed stop and trip protection In case of wire disconnection, the 68# function terminal and protection output terminal will act, the inverter will stop after running at the frequency of F27.24 for the time of F27.23 and then the protection will be enabled.
Hundreds place of F27.20 = 2: Material cutoff protection In case of wire disconnection, the inverter will be in the protection status. Hundreds place of F27.20 = 3: Automatic reset of material cutoff protection In case of wire disconnection, the inverter will be in the protection status and reset automatically after the set delay time of F27.26. Hundreds place of F27.20 = 4: Only output of material cutoff detection terminal In case of wire disconnection, the inverter will not be subject to trip protection, and only the output terminal for material cutoff detection output will be valid. Hundreds place of F27.20 =5:
Automatic resetting of material cutoff detection terminal This is the same as the option 4. The terminal of material cutoff detection output is invalid only when the swing rod returns to the normal range. Thousands place of F27.20 = 0: Mode 0 Mode 0: When the output frequency is within the brake signal output frequency (F27.25) from top to bottom, the brake will not work. Thousands place of F27.20 = 1: Mode 1 Mode 1: When the output frequency is within the brake signal output frequency (F27.25) from top to bottom, the brake will work. Ten hundreds places of F27.20 = 0: no speed limit There is no reverse speed limit. Ten hundreds places of F27.20 = 1:
reverse speed limit by F27.24 There is no reverse speed limit by F27.24. When the inverter receives the running command, wire disconnection detection will be performed after the set time. 334 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F27.21 Material cutoff detection delay 0.0~10.0 s 6.0 ● 0x1B15 Function code Function code name Parameter description Unit Default setting Attribute Mailing address
