Preset Frequency and Parameter 19 -- Frequency Select
Aux Accel/Decel Enable Units = Code
Range = 0/1/2
Factory Setting = 0
This parameter enables or disables the selection of preset drive frequencies,
auxiliary drive preset accel and decel times, or both. To allow drive preset
frequencies and/or aux accel and decel times to be selected, external
switches must be connected to the Control and Signal Wiring Terminal
Block as detailed in Chapter 4.
Preset frequencies are set by Parameters 29-35. Auxiliary accel and decel
times are set by Parameters 36-41. External switches connected to the
Control and Signal Wiring Terminal Block are enabled or disabled as
explained below and in the Preset Frequency and Aux Accel/Decel Enable
Tables on pages 5-20 –– 5-22.
1. Switch
SW2 on the Control Board is factory set to 4SP. When set to 4SP,
two external switches may be connected to the drive. In addition to the
standard accel and decel rates set by Parameters 1 and 2, switches S1
and S2 may then be used to select three additional accel rates, three
additional decel rates, and four preset speeds, as programmed by
Parameters 29-31 and 36-41.
2. When switch
SW2 on the Control Board is set to 8SP, a total of three
external switches may be connected to the drive. In addition to the
standard accel and decel rates set by Parameters 1 and 2, switches S1, S2
and S3 may then be used to select three additional accel rates, three
additional decel rates, and seven preset speeds, as programmed by
Parameters 20 and 29-41.
Parameter 19 settings.
When set to 0, only the preset frequency function is enabled. External
switches connected to the Control and Signal Wiring Terminal Block can
only be used to select preset frequencies.
When set to 1, only the auxiliary accel and decel function is enabled.
External switches connected to the Control and Signal Wiring Terminal
Block can only be used to select auxiliary accel and decel times.
When set to 2, both the preset frequency function and the auxiliary accel
and decel function is enabled. External switches connected to the Control
and Signal Wiring Terminal Block can be used to select both preset
frequencies and auxiliary accel and decel times.
