Dual Ramp Start
The SMC-Flex controller provides the user with the ability to select
between two Start settings. The parameters below are available in the
Set Up programming mode. To obtain Dual Ramp control, Ramp #1 is
located in the Basic Set Up and Ramp #2 is located in the Option 2 Input
(Dual Ramp).
Parameter Option
Set Up
The user must select the Set Up programming mode
to obtain access to the Dual Ramp parameters.
—
Basic Set Up/Starting Mode
Set up as stated in previous pages.
—
Option 1 Input (Dual Ramp) u
This allows the user the option to choose between
two Soft Start profiles defined by:
1. Start Mode/Ramp Time/Initial Torque and
2. Start Mode 2/Ramp Time 2/Initial Torque 2.
When this feature is turned on, the ramp time/initial
torque combination is determined by a hard contact
input to terminal 15. When this input signal is low,
ramp time/initial torque 2 are selected. Once the
Option 2 Input has been set to Dual Ramp, you must
ESC back to the Parameter (File) menu. Re-enter
into the Set Up menu to show both Basic Set Up and
Dual Ramp.
—
Basic Set Up/Start Mode v
This selects the start mode for option #1.
—
Basic Set Up/Ramp Time
This programs the time period during which the
controller will ramp the output voltage up to full
voltage for the first Start setup.
0 to 30 s
Basic Set Up/Initial Torque
This parameter establishes and adjusts the initial
reduced output voltage level for the first Soft Start
setup.
0 to 90/% locked
rotor torque
Dual Ramp/Start Mode 2 v
This selects the start mode for option #2.
—
Dual Ramp/Ramp Time 2
This programs the time period during which the
controller will ramp the output voltage up to full
voltage for the second Start setup.
0 to 30 s
Dual Ramp/Initial Torque 2
The initial reduced output voltage level for the
second Start setup is established and adjusted with
this parameter.
0 to 90/% locked
rotor torque
u The Dual Ramp feature is available on the standard controller.
v Kickstart can be programmed for both start modes.
