11.8 H: Terminal Functions
876 YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
Figure 11.85 shows an example of how the function operates.
Figure 11.85 Reference Sample Hold
You cannot set the Reference Sample Hold function at the same time as these functions:
• H1-xx = A [Accel/Decel Ramp Hold]
• H1-xx = 10, 11 [Up Command, Down Command]
• H1-xx = 44 to 46 [Add Offset Frequency 1 to 3]
• H1-xx = 75, 76 [Up 2 Command, Down 2 Command]
If you set them at the same time, the drive will detect oPE03 [Multi-Function Input Setting Err].
■ 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 [External Fault (Terminal Sx)], where x is the
number of the terminal (terminal Sx) to which the external fault signal is assigned. For example, when an external
fault signal is input to terminal S3, 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 11.62 shows the relation between the conditions and the value set to H1-xx.
