Parameters 331
(Visible when a resolver is selected)
Defines the frequency of the excitation signal.
1 kHz
1…20 kHz
Excitation signal frequency.
1 = 1 kHz
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects the type of encoder.
Quadrature
Quadrature encoder (with two channels, A and B)
0
Single track
Single-track encoder (with one channel, A).
Note: With this setting, the measured speed value is
always positive regardless of direction of rotation.
1
(Visible when absolute encoder is selected)
Selects the source of the absolute position information.
None
Not selected.
0
Commut signals
Commutation signals.
1
EnDat
Serial interface: EnDat encoder.
2
Hiperface
Serial interface: HIPERFACE encoder.
3
SSI
Serial interface: SSI encoder.
4
Tamagawa
Serial interface: Tamagawa 17/33-bit encoder.
5
(Visible when a resolver is selected)
Defines the amplitude of the excitation signal.
4.0 V
4.0…12.0 V
Excitation signal amplitude.
10 = 1 V
(Visible when a TTL, TTL+ or HTL is selected)
Selects the speed calculation mode.
*With a single-track encoder (parameter
is set to
), the speed is always
positive.
A&B all
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
), this setting acts like setting
0
A all
Channel A: Rising and falling edges are used for speed
calculation.
*Channel B: Defines the direction of rotation.
1
A rising
Channel A: Rising edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
2
A falling
Channel A: Falling edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
3
Auto rising
One of the above modes is selected automatically
depending on the pulse frequency as follows:
4
No.
