User Manual of EM760 High-Performance Inverter Ones place ofF27.20 = 0: automatic detection Wire disconnection is detected automatically by the inverter. In this mode, F09.35 and F09.36 must be set accurately. Ones place ofF27.20 = 1: external signal Wire disconnection is detected by the external proximity switch. Tens place ofF27.20 = 0: Detection with the output greater than the lower limit of material cutoff detection When the stop command is received, and the output frequency is less than the set value ofF27.22, wire disconnection will not be detected. Tens place ofF27.20 = 1: no detection Wire disconnection will not be detected. Hundreds place ofF27.20 = 0:
Protection terminal action only In case of wire disconnection, the inverter will continue to run at the set frequency ofF27.24, and only the 68# function terminal and protection output terminal will act. Hundreds place ofF27.20 = 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 ofF27.20 = 2: Material cutoff protection In case of wire disconnection, the inverter will be in the protection status. Hundreds place ofF27.20 = 3 :
Automatic reset of material cutoff protection In case ofwire disconnection, the inverter will be in the protection status and reset automatically after the set delay time ofF27.26. Hundreds place ofF27.20 = 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 ofF27.20 =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 ofF27.20 = 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 ofF27.20 = 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 ofF27.20 = 0: no speed limit There is no reverse speed limit. Ten hundreds places ofF27.20 = 1: reverse speed limit by F27.24 There is no reverse speed limit by F27.24. 188 Function Function code Parameter description Unit Default Attribute
