HobbyKing YEP Series Instruction Manual

Instruction Manual for YEP Series of Electronic Speed
1 Features:
- 6 step adjustable timing or automatic timing adjustment
- Lipo(Auto) / NiMh adjustable.
- Adjustable brake, amount and speed are proportional to the soft-start.
- Full utilization of the throttle stick range by programming in the RC-Setup
- PWM range from 8 KHz to16KHz adjustable in steps of 1KHz!
- The PWM switching rate can be applied as little as you require or as much as you require
- Higher frequency for low inductive motors,
- Lower frequency for less switching losses.
- Active free-wheel, this can be disabled with the Prog Card II.
- Active free-wheel reduces the losses in the partial load range but can lead to problems in rare
cases. In relation to speed control it can lead to rougher transitions from part loads to full loads,
avoid switching the speed controller mode when using full power.
2 RC-Setup:
General beep sequences outside of the RC-Setup programme:
signals you are in programming mode.
When the throttle stick in the neutral position, a group of descending beep sequences means that it
is receiving a signal. Afterwards (after the signal is recognised) more beeps indicate
the recognition of the selected battery type. Then the next group of ascending beeps means that
the ESC is armed! The ESC is now ready for use. Take care once the ESC is armed!
The correct setting is particularly important for Lipo battery pack, therefore an acoustic control
takes place every time you power on the ESC.
Lipo-setting (Lipo auto-mode 2-6 (14) cells):
2 identical beeps => 2S Lipo recognised
3 identical beeps => 3S Lipo recognised
And so on...
For the ESC to successfully recognise the number of cells the battery pack should always be
fully charged, even with 3 cells or more.
Otherwise, with high cell numbers it can happen that a cell is missed and thus the under voltage
protection would trigger too late. The cells of battery packs can be programmed by Prog Card II.
With more than 6 cells the beep sequence becomes two high pitch beeps and then two low
pitch beeps, This is because following the count of so many beeps is difficult. A high
numbers of cells should not be operated in the auto mode anyway. We recommend to set the
number of cells permanently with the Prog Card II.
The under voltage protection is triggered at 3.1V per cell. This conservative value can prolong
the life of your Lipo battery pack! It is important to make sure the correct number of cells is
detected to avoid a wrong signal for under voltage protection.
A fixed under voltage limit can only be programmed with the Prog Card II. You can also set the
limits for LiFePo battery pack using the Prog Card II.
How to programme the ESC using a transmitter.
Ni-xx batteries--setting (NiCd/NiMh):
2 Beeps high/low => NiMh-Mode: under voltage limit approximately equals 0.65, multiply the
open circuit voltage of each cell.
