ACE-tronics G9 ASD Installation and Operation Manual 231
Speed Control Mode
Program  Crane/Hoist  Speed Control
This parameter setting determines the speed-control method to be used for
motor control.
Settings:
Standard (ACE G9) — Normal ASD default settings and operation.
2-Step Variable
Required inputs — F, R, and I1 (default via Startup Wizard).
F or R — Provides a Run command and outputs 6 Hz when
activated. Decelerates to zero when deactivated or when both are on.
I1 — Provides a command to accel toward the Upper-Limit setting
when activated. Holds (frequency) when deactivated.
3-Step Variable
Required inputs — F, R, I3 (default), and I4 (default).
F or R — Provides a Run command and outputs 6 Hz when
activated. Decelerates to zero when deactivated or when both are on.
I3 — Provides a command to accel toward the Upper-Limit setting
when activated.
I4 — Holds the Run frequency when activated. Returns to the Run
command (6 Hz or stop) when deactivated.
5-Speed
Required inputs — F, R, and Preset Speeds 1 – 4.
F or R — Provides a Run command and outputs 6 Hz when
activated. Decelerates to zero when deactivated or when both are on.
I3 – I6 — Sequentially activates Preset Speeds 1 – 4. All of the
preceding Preset Speeds must be active for a given Preset Speed to
be output from the ASD (i.e., PS1 = PS1, PS1 & PS2 = PS2, PS1 &
PS2 & PS3 = PS3, etc.). If not all of the preceding Preset Speeds are
active, the highest Preset Speed number with all of the preceding
Preset Speeds active will be output from the ASD (i.e., PS1 & PS2 &
PS4 = PS2).
2- and 3-Speed
Same as 5-Speed using only the required number of Preset Speed settings.
Unipolar Analog
Required inputs — F, R, and RR
input.
F or R — Provides a Run command and outputs 6 Hz when
activated. Decelerates to zero when deactivated or when both are on.
RR — Controls the output speed from the Lower Limit to the Upper
Limit.
Bi-Polar Analog
Required inputs — F, R, and RX input.
F or R — Provides a Run command and outputs 6 Hz when
activated. Decelerates to zero when deactivated or when both are on.
RX — Controls the output speed from the Lower Limit to the Upper
Limit (Forward or Reverse).
Direct Access Number — F986
Parameter Type — Selection List
Factory Default — 2-Step Variable
Changeable During Run — N
2-Step Variable operation
3-Step Variable operation
Note: Incorrectly activated discrete
input terminals will result in a
Switch Out Of Order Alarm
halting the ASD (e.g., F and R
activated simultaneously when
not required).
To clear this condition,
deactivate all discrete input
terminals.
