196 Parameters
92
92 Resolver conf Resolver configuration.
92.01 Resolv polepairs Selects the number of pole pairs.
1 … 32 Number of pole pairs. 1 = 1
92.02 Exc signal ampl Defines the amplitude of the excitation signal.
4.0 … 12.0 Vrms Amplitude of excitation signal. 10 = 1 Vrms
92.03 Exc signal freq Defines the frequency of the excitation signal.
1 … 20 kHz Frequency of excitation signal. 1 = 1 kHz
93
93 Pulse enc conf
Pulse encoder configuration.
93.01 Enc1 pulse nr Defines the pulse number per revolution for encoder 1.
0 … 65535 Number of pulses for encoder 1. 1 = 1
93.02 Enc1 type Selects the type of the encoder 1.
Quadrature Quadrature encoder (has two TTL channels, channels A
and B) 0
Single track Single track encoder (has one TTL channel, channel A) 1
93.03 Enc1 sp CalcMode Selects the speed calculation mode for encoder 1.
A&B all Channels A and B: Rising and falling edges are used for
speed calculation. Channel B: Defines the direction of
rotation.
Notes:
• When single track mode has been selected by parameter
93.02 Enc1 type , this setting acts like the setting A all .
• When single track mode has been selected by parameter
93.02 Enc1 type , the speed is always positive.
0
A all Channel A: Rising and falling edges are used for speed
calculation. Channel B: Defines the direction of rotation.
Note: When single track mode has been selected by
parameter 93.02 Enc1 type , the speed is always positive.
1
A rising Channel A: Rising edges are used for speed calculation.
Channel B: Defines the direction of rotation.
Note: When single track mode has been selected by
parameter 93.02 Enc1 type , the speed is always positive.
2
A falling Channel A: Falling edges are used for speed calculation.
Channel B: Defines the direction of rotation.
Note: When single track mode has been selected by
parameter 93.02 Enc1 type , the speed is always positive.
3
Auto rising One of the above modes is selected automatically depending
on the TTL pulse frequency as follows: 4
No. Name/Value Description FbEq
Pulse frequency of the channel(s) Mode used
< 2442 Hz A&B all
2442…4884 Hz A all
> 4884 Hz A rising
