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.

only one track is evaluated (dep. of switch 202)

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

HTL - Single channel encoder interface

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.
