6.1.4 Brake Operations via Terminal A1 (Speed Command Input)
Time charts up to this point have been when the terminal A1 signal selection (H3-01) has been set to zero (0V to
+10V). There, the brake cannot be applied or released by using the Speed Command via terminal A1.
In the diagram below, H3-01 has instead been set to "1" (allowing input of -10V to +10V). This permits the brake to
be applied and released by using the Speed Command Input via Terminal A1.
Operations when H3 -01 (Terminal A1 Signal Level) is set to “1”:
When there are momentary changes to the Speed Command Input:
When there are smooth changes to the Speed Command Input:
Note: 1. If the Speed Command Input (terminal A1) is negative, t hen it is read as REV.
2. Once the Speed Command Input (terminal A1) value is smaller than b2 -01 and E1-09, then the Run Command will
be seen as open after 100ms has passed.
3. Until the Run Command is seen as open, the drive will operate with a speed command of either FRF (FRR) or FHF
(FHR), whichever is larger.
