Parameters
1209 TIMED MODE SEL 1, 2 1 2 (CS1/2/3/4)
Defines timed function activated constant speed mode. Timed function can be used to change between the external
reference and constant speeds when parameter 1201 CONST SPEED SEL = 15…18 (TIMED FUNC 1…4) or 19 (TIMED
FUN1&2).
1 =
EXT/CS1/2/3
• If parameter 1201 = 15…18 (
TIMED FUNC 1…4), selects an external speed when this timed function (1…4) is not
active and selects Constant speed 1 when it is active.
• If parameter 1201 = 19 (
TIMED FUN1&2), selects an external speed when neither timed function is active, selects
Constant speed 1 when only Timed function 1 is active, selects Constant speed 2 when only Timed function 2 is
active and selects Constant speed 3 when both Timed functions 1 and 2 are active.
2 =
CS1/2/3/4
• If parameter 1201 = 15…18 (
TIMED FUNC 1…4), selects Constant speed 1 when this timed function (1…4) is not
active and selects Constant speed 2 when it is active.
• If parameter 1201 = 19 (
TIMED FUN1&2), selects Constant speed 1 when neither timed function is active, selects
Constant speed 2 when only Timed function 1 is active, selects Constant speed 3 when only Timed function 2 is
active and selects Constant speed 4 when both Timed functions 1 and 2 are active.
