AHS/AHM36 SSI ABSOLUTE ENCODERS

FLEXIBLE, SMART, COMPACT

Product description

The AHS/AHM36 SSI absolute encoder
product family provides increased exi­bility due to its mechanical adaptation,
electrical connectivity, and SSI communi­cation. With their rotating male connec­tor or cable outlets as well as the various
mounting hole patterns and adapter

anges, these encoders are suitable for

nearly any application. The encoders are
able to connect to a wide range of con­trols due to a programming tool that can
be used to make individual adjustments

to the structure of the SSI protocol, in
addition to adjusting the singleturn/mul­titurn resolution, the counting direction,
and other parameters. Thanks to the
large operating temperature range from

–40 °C ... +100 °C and the protection

class up to IP67, this encoder family can
be used in harsh ambient conditions.
The rugged, reliable, fully magnetic sen­sor system provides a maximum resolu­tion of 14 bits for the singleturn variant
and 26 bits for the multiturn variant.

R¯/VForwards / Reverse: This input programs the counting direction for the

encoder. When it is not connected, this input is set to HIGH. If the encoder
shaft is rotated clockwise (to the right) as viewed when facing the shaft, it
counts in ascending order. If it should count in ascending order when the
shaft is rotated counterclockwise (to the left), then this connection must be
permanently set to LOW level (GND).

SET This input is for electronic zeroing. If the SET cable is set to US for more

than 250 ms, the mechanical position corresponds to the O value, i. e., the
predetermined SET value.

MS

Non-programmable encoder

Non-programmable encoders always output the SSI position MSB-justied (left-justied).

• 14 bits + 1 errorbit are always output (irrespective of the type and resolution selected)

• For resolutions below 14 bits, non-assigned bits are lled with 0.

Programmable encoder

• Per default, programmable encoders output the SSI position MSB-justied (left-justied).

• The operating modes “binary” and “non-binary” can be selected to set the resolution.

• All formats (left and right-justied) can be covered by shifting the bits in the programming interface accordingly using the arrow

keys.

Errorbit

ERROR: general error This bit is set as soon as an error occurs in the encoder. This bit remains set as long as the error is present.
In non-programmable encoders, the errorbit is always output as the 15th bit. In programmable encoders, it can also be output as
the 15th bit or can be transmitted directly after the position bits.

The evaluation of the errorbit must be implemented in the control unit.

The errorbit output need not be used by the control unit.
If the errorbits cannot be evaluated in the control unit, the control unit must be set to the encoder resolution.
The errorbits must then be masked out at the control.

SSI mode:

Non-programmable encoders work in asynchronous SSI mode.
In programmable encoders, the programming interface enables users to choose between asynchronous and synchronous SSI
mode. Asynchronous SSI mode is selected as the default setting.

Asynchronous SSI mode:

The position is always formed and made available every 125 µs. The time for calculating the position is not related to the master

clock. In asynchronous SSI mode, the break between two clock bursts must remain constant with a maximum deviation of ± 20%

and must not exceed 600 ms.

Synchronous SSI mode:

The position is formed in sync with the master clock output, i.e., the time of the position values is related to the time of the master
clock.
The position formation process begins 20 µs following the end of a clock burst. The position is then made available after 125 µs.
The next position is formed a further 20 µs after the end of the subsequent clock burst. The break between two clock bursts must
be at least 150 µs.

Non-programmable encoders always output the SSI position MSB-justied (left-justied).

• 26 bits + 1 errorbit are always output (irrespective of the type and resolution selected).

For resolutions below 26 bits, non-assigned bits are lled with 0.

Programmable encoder

• Per default, programmable encoders output the SSI position MSB-justied (left-justied).

• The operating modes “binary”, “non-binary” and “round axis functionality” can be selected to set the resolution.

• All formats (left and right-justied, 25 bit mode and r-tree format) can be covered by shifting the bits in the programming inter-

face accordingly using the arrow keys.

Errorbit

ERROR: general error This bit is set as soon as an error occurs in the encoder. This bit remains set as long as the error is present.
In non-programmable encoders, the errorbit is always output as the 27th bit. In programmable encoders, it can also be output as
the 27th bit or can be transmitted directly after the position bits.

Cycle 1-12: multiturn position bits
Cycle 13-26: singleturn position bits
Cycle 27: errorbit

The evaluation of the errorbit must be implemented in the control unit.

Round axis functionality

The programmable multi-turn encoder supports the gear functions for rotary axes (endless shaft). Here, the number of revolutions
is set a break; a total number of steps is also set. The total number of steps is distributed over the set number of revolutions, e. g.
100 steps to 12.5 revolutions (see example for the programming interface on the next page).
The round axis functionality can be used to implement a number for the overall resolution that is not a 2n multiple of the number
of steps per revolution. It is also possible to set a non-integer number both for the number of revolutions and for the number of
steps per revolution.
