Description
(Visible when an absolute encoder is selected)
Selects the source of the absolute position information.
Not selected.
Commutation signals.
Serial interface: EnDat encoder.
Serial interface: HIPERFACE encoder.
Serial interface: SSI encoder.
Serial interface: Tamagawa 17/33-bit encoder.
(Visible when a resolver is selected)
Defines the amplitude of the excitation signal.
Excitation signal amplitude.
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects the speed calculation mode.
*With a single-track encoder (parameter
type is set to Single track), the speed is always positive.
Channels A and B: Rising and falling edges are used for
speed calculation.
*Channel B: Defines the direction of rotation.
Note: With a single-track encoder (parameter
encoder type), this setting acts like setting
Channel A: Rising and falling edges are used for speed
calculation.
*Channel B: Defines the direction of rotation.
Channel A: Rising edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
Channel A: Falling edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
One of the above modes is selected automatically depending
on the pulse frequency as follows:
Pulse frequency of the
