Start-Up
12 = DI1,2,3 – Selects one of seven Constant Speeds (1…7) using DI1, DI2 and DI3.
• Uses three digital inputs, as defined below (0 =
DI de-activated, 1 = DI activated):
13 =
DI3,4,5 – Selects one of seven Constant Speeds (1…7) using DI3, DI4 and DI5.
• See above (
DI1,2,3) for code.
14 =
DI4,5,6 – Selects one of seven Constant Speeds (1…7) using DI5, DI6 and DI7.
• See above (
DI1,2,3) for code.
15…18 =
TIMER 1…4 – Specifies the timer used to select a Constant Speed as the reference. The reference
selection depends on the state of the selected timer, and the value of 1209
TIMED MODE SEL. See table. To enable
and set timers, see Group 36, Timer Functions.
19 =
TIMER 1&2 – Specifies that Timers 1 and 2 are used together to select a Constant Speed as the reference. The
reference selection depends on the states of these timers, and the value of 1209
TIMED MODE SEL. See table. To
enable and set timers, see Group 36, Timer Functions.
-1 =
DI1(INV) – Selects Constant Speed 1 with digital input DI1.
• Inverse operation: Digital input de-activated = Constant Speed 1 activated.
-2…- 6 =
DI2(INV)…DI6(INV) – Selects Constant Speed 1 with digital input. See above.
-7 = DI1,2(INV) – Selects one of three Constant Speeds (1…3) using DI1 and DI2.
• Inverse operation uses two digital inputs, as defined below (0 =
DI de-activated, 1 = DI activated):
-8 =
DI2,3(INV) – Selects one of three Constant Speeds (1…3) using Di2 and DI3.
• See above (
DI1,2(INV)) for code.
-9 =
DI3,4(INV) – Selects one of three Constant Speeds (1…3) using DI3 and DI4.
• See above (
DI1,2(INV)) for code.
-10 =
DI4,5(INV) – Selects one of three Constant Speeds (1…3) using DI4 and DI5.
• See above (
DI1,2(INV)) for code.
-11 =
DI5,6(INV) – Selects one of three Constant Speeds (1…3) using DI5 and DI6.
• See above (
DI1,2(INV)) for code.
