5.6.2 Starting Mode
The
TE Series
is capable of several different starting modes, but is set
from the factory for the most common applications. A second ramp
profile is available for use should it be required. Unless wired to do so,
the
TE Series
defaults to Ramp 1. This section describes functions for
Ramp 1, with references to function numbers that do the same thing for
Ramp 2 (if required).
Refer to Appendix 2 for a detailed description
of
the differences in Ramp Profiles and their uses. All current percentages
are based on the Motor FLA as programmed in
F001
.
F010 = Ramp Profile Selection
Factory Setting = 1
Range = 1 – 4
This Function selects the type of Ramp Profile desired. Ramp
profiles can be either Voltage Ramp or Current Ramp. See
Appendix 2 for details. Each Ramp Profile consists of 3 settings:
Initial Torque, Ramp Time and Maximum Current Limit. Because
there are two ramps available, there are 4 settings to cover the
combinations of profiles possible. If you are not using the 2
nd
ramp, the
TE Series
will ignore all settings in reference to Ramp
2.

Table 5.6.2: Ramp Type selection Settings
Select Voltage Ramp by setting
F010 = 1
(factory default)
When Voltage Ramp is selected,
Set Initial Torque (Voltage) with
F011
(see below)
Set Ramp Time with
F013
(see below)
Set Maximum Current Limit with
F014
(see below)
Or;
Select Current Ramp by setting
F010 = 2
When Current Ramp is selected,
Set Initial Torque (Current) with
F012
(see below)
Set Ramp Time with
F013
(see below)
Set Maximum Current Limit with
F014
(see below)
Note:
When either Ramp is set to “Voltage Ramp”, the corresponding
“Initial Torque (Current)” setting is ignored. Conversely, when set to
“Current Ramp”, the “Initial Torque (Voltage)” is ignored.
