For GPD515 Adjustable Frequency Drives
Traverse Control
FLASH Memory Software Option
Part Number: GPD515C-XXXX-CS006
(1)
With this factory-installed FLASH software, the
GPD515 has the ability to modulate the output
frequency around the set frequency reference.
This function provides an evenly wound roll for
those winding applications that would
experience localized build-ups without this
feature. The terms disturb, p-jump, ribbon
break and wobbulator are also used to
describe this function.
Specifications:
• P-Jump Function / Inertia Compensation
• P-Jump ON/OFF Select
• P-Jump Limit
• Adjustable Duty Cycle
• Sawtooth Waveform Generation / Ribbon
Break
• Percent Trim Adjustment
• Independent P-Jump Adjustment
• Independent Accel/Decel Times
• Control Mode: P-Jump in V/f only
• Serial Communications: DeviceNet,
Profibus, Modbus Plus, Modbus RTU.
This document is an addendum to Technical
Manual TM4515, listing the effect of this software on the parameters in the drive and
function descriptions in the manual.

3.0 Startup Procedure
1. Perform the start-up procedure using section 2.2c of the GPD515 technical manual. This
procedure will go through changing the drive into V/f control, and setting up the V/hz pattern.
2. Verify that parameter P1-01 is set to a 1 (Enabled).
3. Adjust parameter P1-02 to the desired amount of disturbed waveform amplitude desired.
This parameter is set as a percentage of the frequency reference.
4. Adjust Parameter P1-03 to the desired amount of disturbed waveform “jump”. This is used
to compensate for the mechanical inertia of the system. This parameter is set as a
percentage of parameter P1-02.
5. Adjust parameters P1-04 and P1-05 to the desired slope times.
6. Done.

4.3 New Program Parameters
The Traverse (Disturb) function give the drive the ability to change speed in a regular
pattern from a steady frequency reference. Traverse changes the speed of the
motor/winder so that the material being wound build up evenly.

Modbus Address: 0581H
This parameter determines how much faster or slower than the set frequency reference
(Fref) the actual frequency reference will be. See Figure 1.
Maximum Frequency = Fref + [P1-02 x Fref]
Minimum Frequency = Fref – [P1-02 x Fref]

P1-03 Disturb Waveform Jump
Setting Range: 0.0 to 50.0%
Factory Default: 0.0%
Modbus Address: 0582H
This parameter determines hoe much “jump” will occur in the frequency reference, and is
used to compensate for the inertia of the mechanical system. See Figure 1.
Jump Distance = P1-03 x P1-02 x Fref

These parameters determine the rate at which the speed reference will change during the
“disturb” operation. P1-04 determines the decel time, and P1-05 determines the accel
time. NOTE: The selected accel/decel rates (C1-01 through C1-08) are disabled during
traverse operation. See Figure 1.
