4.2.5   Enabling the Dual Ramp and Jog Features 
TB1 includes provisions for enabling the Dual Ramp and Jog functions 
by using external contact closures. Both features use a common 
+24VDC from Terminal # 7, however they can be used independently of 
each other or together. See sections 5.6.2 and 5.6.3 for full function 
descriptions and setup.  
 
ƒ  4.2.5.a  
Dual Ramp Command 
Closing a dry (voltage free) contact between TB1, terminals 6 and 7 
will enable Ramp 2, and the TE Series starter will respond to the 
settings for Ramp 2 in F015 - F018. If no contact closure is present, 
the TE Series starter defaults to the Ramp 1 parameters (F011 – 
F014). See Section 5.6.2.a for setup of the Dual Ramp Feature. 
 
The Dual Ramp feature is useful in instances where the load 
changes significantly. Example: a loaded or unloaded conveyor belt. 
The characteristics for starting an unloaded conveyor can be 
programmed for ramp 1. The characteristics for starting a loaded 
conveyor can be programmed for ramp 2. Ramp 2 can also be 
programmed for Full Voltage / Across-the-Line starting by setting 
the ramp time to 0 and Current to 600%. 
 
Dual Ramp is also useful in 2-speed motor applications. Simply use 
an auxiliary contact from one of the speed contactors to select 
Ramp 2 so that separate ramp profiles can be used. 
 
 
ƒ  4.2.5.b  
Jog / Remote Command 
Connecting a dry (voltage free) contact between TB1, Terminals 7 
and 8 will enable the Jog feature. A Start command (Run Command 
or Start button) is required to activate the Jog feature. See Section 
5.6.3 for setup of the Jog Function.  
 
The Jog feature can be used for tasks such as lining up machines 
for blade or bit changes or inching belts along to check tracking. 
 
This input is also used to change the function of the Serial 
Communications port control through F068. For additional 
information, see instructions of that function in section 5.6.11
 
 
 
 
ƒ  4.2.5.c  
Using Both Commands 
It may be useful to initialize the Ramp 2 and Jog command 
simultaneously when jogging. If this is the case, terminals 6 and 8 
can be jumped together and controlled with one contact closure to 
Terminal 7 (the common 24VDC).
