170 Actual signals and parameters
15…18 = TIMER – Selects constant speed 1, constant speed 2 or the external
reference depending on the state of, eg, timer 1 (if the parameter value is 15 =
TIMER 1), timer 3 (if the parameter value is 17 = TIMER 3) etc, and the constant
speed mode. See parameter 1209 and Group 36: Timed functions.
19 = TIMER 1 & 2 – Selects a constant speed or the external reference depending on
the state of timers 1 and 2 and the constant speed mode. See parameter 1209
and Group 36: Timed functions.
-1 = DI1(INV) – Selects Constant speed 1 with digital input DI1.
• Inverse operation: Digital input de-activated = Constant speed 1 activated.
-2 … - 5 = DI2(INV)…DI5(INV) – Selects Constant speed 1 with digital input.
-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.
