WARNING! Sudden Movement Hazard. When you use the Baseblock command with hoist applications, make sure that you
close the holding brake when you input the Baseblock command and the drive shuts off its output. Failure to do obey can cause
death or serious injury if the load moves or falls when motor suddenly coasts after you input the Baseblock command.
■ 20 to 2F: External Fault
Setting Function Description
20 to 2F External Fault
Sets a command to stop the drive when a failure or fault occurs on an external device.
If an external fault is input to the drive, the keypad will show EFx [ExtFault DIx], where x is the number of the
terminal (terminal DIx) to which the external fault signal is assigned. For example, when an external fault signal
is input to terminal DI3, the keypad will show EF3.
Use these conditions to select the value to set in H1-xx:
• Signal input method from peripheral devices
• External fault detection method
• Motor stopping method (operation after external fault detection)
Table 12.40 shows the relation between the conditions and the value set to H1-xx.
