3.7 Mounting Wizard for ECI/EQI
Use the "Mounting" function group to check inductive motor encoders (ECI or EQI) on servo
drives and to adjust them mechanically and electrically.
For detailed mounting information please refer to the ECI/EQI mounting instructions and product
information.
Attention
The encoders may only be mounted and adjusted by especially trained staff. Special tools
(product key for ATS software, adjusting tools) and documentation are required to adjust the
encoders.
The inductive ECI/EQI series are rotary encoders for integration without integral bearing. The
scanning gap between rotor and stator must be set by hand. The actual scanning gap is
determined indirectly from the output voltage in the encoder. Various ambient conditions
(thermal influence at max. working temperature, changes in supply voltage +/- 5 %, encoder
tolerances) have an effect on the scanning gap. To ensure the optimum scanning gap,
tolerance values (drive-specific lead factors, depending on the materials of the motor and
the temperature range) were determined for the different motor series. The manufacturer
of the servo drive enters these values in the ATS software and uses them to adjust the
encoders. In the factory default setting, the ATS software works with the standard
tolerances HEIDENHAIN uses in encoder production. These settings cannot be altered
without the correct product key. HEIDENHAIN reserves the right to provide product keys
after consultation only.
An exact diagnosis of the encoder mounting is only meaningful together with the values
determined for the motor. If the ECI/EQI encoders are adjusted with incorrect setting
values, the servo drive may fail before the maximum operating temperature is reached, or
the encoder may be destroyed because the scanning gap is too small.
Note
The "Mounting" function group is only active, when an inductive ECI/EQI motor encoder is
connected to the ATS software. Display and functions depend on the ECI/EQI model
connected and on the active product key.
