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 you need it. 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)
ƒ 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.
