Def / Type
FbEq 16b / 32b Description Name / Range /
Selection No.
2048 / uint16 (Visible when 92.1 Encoder 1 type = HTL 1 )
Defines the pulse number per revolution.
Pulses/revolution 92.10
- / - Number of pulses. 0...65535
4.0 V / uint16 (Visible when 92.1 Encoder 1 type = Resolver )
Defines the rms amplitude of the excitation signal.
Excitation signal
amplitude 92.11
10 = 1 V / 100 = 1 V Excitation signal amplitude. 4.0 ... 12.0 V
None / uint16 (Visible when 92.1 Encoder 1 type = Absolute encoder )
Selects the source of the absolute position information.
Absolute position
source 92.11
0 Not selected. None
1 Commutation signals. Commut. signals
2 Serial interface: EnDat encoder. EnDat
3 Serial interface: HIPERFACE encoder. Hiperface
4 Serial interface: SSI encoder. SSI
5 Serial interface: Tamagawa 17/33-bit encoder. Tamagawa
Quadrature / uint16 (Visible when 92.1 Encoder 1 type = HTL 1 )
Selects the type of encoder.
Pulse encoder type 92.11
0 Quadrature encoder (with two channels, A and B). Quadrature
1 Single-track encoder (with one channel, A).
Note: With this setting, the measured speed value is
always positive regardless of direction of rotation.
Single track
1 / uint16 (Visible when 92.1 Encoder 1 type = Resolver )
Defines the number of pole pairs of the resolver.
Resolver polepairs 92.12
1 = 1 / 1 = 1 Number of resolver pole pairs. 1...32
Disable / uint16 (Visible when 92.1 Encoder 1 type = Absolute encoder )
Enables the encoder zero pulse for the absolute
encoder input (X42) of the FEN-11 interface module.
Note: No zero pulse exists with serial interfaces, ie.
when parameter
92.11 Absolute position source is set
to EnDat , Hiperface , SSI or Tamagawa .
Zero pulse enable 92.12
0 Zero pulse disabled. Disable
1 Zero pulse enabled. Enable
Auto rising / uint16 (Visible when 92.1 Encoder 1 type = HTL 1 )
Selects the speed calculation mode.
*With a single-track encoder (parameter
92.11 Pulse
encoder type is set to Single track ), the speed is always
positive.
Speed calculation
mode 92.12
0 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 92.11
Pulse encoder type e, this setting acts like setting A all .
