5.7 H: Terminal Functions
206 YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual
Setting 1A: Accel/decel ramp selection 2
Used to select accel/decel ramps 1 to 4 in combination with the Accel/decel ramp selection 1 command. Refer to C1-01 to
C1-08: Accel, Decel Ramps 1 to 4 on page 172 for details.
Setting 20 to 2F: External fault
The External fault command stops the drive when problems occur with external devices.
To use the External fault command, set one of the multi-function digital inputs to any value between 20 to 2F. The digital
operator will display EF where is the number of the terminal to which the external fault signal is assigned.
For example, if an external fault signal is input to terminal “EF3” will be displayed.,
Select the value to be set in H1- from a combination of any of the following three conditions:
• Signal input level from peripheral devices (N.O., N.C.)
• External fault detection method
• Operation after external fault detection
The following table shows the relationship between the conditions and the value set to H1-.
Terminal statuses, detection conditions, and stopping methods marked with an
“ O ”
are applicable to the corresponding
settings.
Setting 50: Nominal speed
Closing a terminal set for “Nominal speed” makes the drive run at the speed reference set to d1-19. Conditions change,
however, according to the speed selection mode set in d1-18. Refer to Multi-Speed Inputs 1, 2 (d1-18 = 0 or 3) on
page 124 for details.
Setting 51: Intermediate speed
Closing a terminal set for “Intermediate speed” makes the drive run at the speed reference set to d1-20. This setting can
also be used in combination with other input terminals set for 50 (Nominal speed) and 52 (Releveling speed) to switch
between the speed reference set in d1-21 and d1-22. Conditions change, however, according to the speed selection mode
set in d1-18. Refer to Multi-Speed Inputs 1, 2 (d1-18 = 0 or 3) on page 124. for details
Setting 52: Releveling speed
Closing a terminal set for “Releveling speed” makes the drive run at the speed reference set to d1-23. Conditions change,
however, according to the speed selection mode set in d1-18. Refer to Multi-Speed Inputs 1, 2 (d1-18 = 0 or 3) on
page 124 for details.
Setting
<1> Determines the terminal status for each fault, i.e., whether the terminal is normally open or normally closed.
<2> Determines whether detection for each fault should be enabled only during run or always detected.
