Positioning

Serial Number

Access rights: Root
Description: Serial number of the position measuring system.
Data: (UInt32) => 0 .. 4294967296

Type

Access rights: Advanced
Description: The measuring system type is defined here.

• Encoder (0x00)
  Encoder measuring system without index track. Observe Parameter 1.
• Encoder Index (0x01)
  Encoder with index track. The index track is evaluated for all reference movements. To ensure that an index track is located at the correct position, with certain referencing methods, the drive might move briefly forward and back or make small movements in the wrong direction. The modules also move with reference method "NONE", as the next index pulse is searched for. Observe Parameter 1.
• Resolver (0x02)
  Resolver system where the excitation current must be generated internally. Observe Parameter 1 and Parameter 2.

  In motors with resolver ) ,,chatter'' might occur with ''positioning ramp type,, ,,Jerk''. If this is the case, select a different ''positioning ramp type,,.

  
  
  

• Encoder Differential (0x06)
  Differential encoder without index track. Observe parameter1!

• Encoder Differential Index (0x07)
  Differential encoder with index track. The index track is evaluated for all reference movements. To ensure that an index track is located at the correct position, with certain referencing methods, the drive might move briefly forward and back or make small movements in the wrong direction. The modules also move with reference method ,,None'', as the next index pulse is searched for. Observe Parameter 1

Mount

Access rights: Advanced
Description: The mount type of the positioning system.

• On Input Side: The positioning system is mounted the motor.
• On Output Side: The positioning system is mounted the drive side.
• On Middle Side: The positioning system is mount between motor and drive side.

Parameter 1

Access rights: Advanced
Description: Parameter 1 for the positioning measuring system.

• Encoder: Ticks in Rotation (4-fold evaluation)
• Resolver: Voltage frequency at the excitation coil in [kHz]. Allowed values: 8 [kHz], 4 [kHz], 2 [kHz], 1 [kHz].

Parameter 2

Access rights: Advanced
Description: Parameter 2 for the positioning measuring system.

• Encoder: not required
• Resolver: Amplitude of the input voltage at the excitation coil [%]. Must be determined by measurement. The output voltage at the receiver coils may not reach saturation point.

Offset

Access rights: Advanced
Description: Rotational position of the positioning measuring system relative to the motor phases. Configured in the preset unit system . This value can be calculated automatically (see the standstill commutation). A ,,space vector'' search will be started again, when the value is set to zero by the user.

Data: (Float)

For a space vector search the module should be movable in all directions. The module move fitfully up to two motor rotations. In this time, no communication with the module is possible.

Motion Threshold

Access rights: Profi
Description: The value [%] of maximum velocity. If the velocity drops below this value, the modul will be handled as not moving.
Data: (Float)

ADC Offset

Access rights: Root
Description: ADC Offset to ,,center'' the measured signal. Only used for sin/cos and resolver measurement systems.
Data: (Int16) -32767 .. 32767
