HTL - Single channel encoder interface
1. Product description
1.1 General
The encoder interface HTL has only one channel. It operates internally with push-pull, so
only the +tracks must be connected. The instruction covers the installation of the interface
card, the connection as well as the start-up of a suitable encoder. Further information and the
parameter adjustments are described in the application manual for the inverter/servo.
1.2 Description of encoder interface
Encoder type: Incremental encoder
Voltage level: HTL
Inputs/Tracks: A+, B+ (HTL)
Particularities: Speed and acceleration monitoring
1.3 Material number
1 MF5K8G- 6 0 0 7
Term of delivery 0: installed Z: Option, spare part
2. Encoder interface 6: none
applicable for housing size 1: D, E (circuit board 1MF5280-6007)
1.4. Scope of delivery (option or replacement delivery)
• encoder interface
• packing material

1.5 Description of the input X3B
1.6 Power supply
1.6.1 Max. load capacity in dependence of voltage supply
Max. load capacity at 24 V: 170 mA
Max. load capacity at 5 V: 400 mA
Max. load capacity in case of external supply 1 A (dependent on external voltage source)
The specified currents are reduced by the current taken from the second interface (see appli-
cation manual Chapter 6.10). In the case the specified currents are not sufficient an external
supply can be connected via the control unit (see application manual Chapter 3.1).
1.7 Signal inputs
1.7.1 Technical data
Input resistance: HTL: 5 kΩ
Logic level: HTL: 15…30 V
Limiting frequency: HTL: 100 kHz
Encoder line number: 8/1250 Ink
Max. line length: 50 m, the value is additionally limited by the signal frequency,
cable capacity and voltage supply.

1.8.1 Signal characteristic of the HTL encoder
In case of HTL encoder interface the signals A+ and B+ are rectangular signals with a phase-
angle displacement by 90 degrees. The inverted signals will be generated internally and does
not need to be provided by the encoder. A zero signal is not supported. The pulse width and
the phase difference must be 2 µs at least.

2. Installation and Start-up
2.1 Mechanical installation
All kind of works on the inverter may be carried out by authorized personnel in accordance
with the EMC and safety rules only.
• Switch inverter de-energized and await capacitor discharge time
• Pull off operator
• Remove plastic cover
• Remove fixing bolt
• Fix interface board beginning from the socket connector straightly
• Screw in fixing bolt
• Attach plastic cover

2.3 Tested encoder
The following HTL-incremental encoder have been tested by KEB on it application:
• Heidenhain ROD 436
However, this does not restrict the use of rotary encoder with same specifications of other
manufacturers.
2.4 Start-up
After the installation or exchange of an encoder interface some adjustments of the inverter/
servo software have to be done before operation:
• Switch on inverter
• Select application mode
• Select parameter Ec.0 and absolutely confirm the displayed value with „ENTER“.
• Select parameter Ec.1 and adjust increments per revolution
2.5 Encoder 1 status (Ec.37)
The parameter Ec.37 displays the current status of the encoder at channel 1.
Value Description Ec.37
0 no communication between interface and control card
16 Encoder and interface are correct; position values are transferred; encoder
relay is pulled in
72 A relay contact serves as acknowledge contact. This error is released, if
triggering signal and acknowledge contact are different longer than 10 ms.
76 Speed tripping at a speed > 3800 rpm. Depending on the exceeding the
break time amounts to 16...128 ms (plus relay break time < 10 ms).
The acceleration tripping is depending on switch S200 and amounts to
• the evaluation of both tracks of a speed of 3750 rpm
• the evaluation of one track of a speed of 5610 rpm
Depending on the exceeding the break time amount to 48...176 ms (plus
relay break time < 10 ms).
255 no communication between interface and control card
If Ec.37 <> 16 the COMBIVERT F5-M/S switches off with error 35 "E.EnCC" (error encoder
change) when the modulation is switched on. F5-G switches only to error, if encoder channel
1 is activated (S.1 = 0) as actual value source for the speed controller.
Error messages and their meaning are described in Chapter 9 of the application manual.
