27 Fbk Mode
Feedback Mode
Selects the number of feedback devices and the type of discrepancy checking.
“Single Fbk” (0) - 1 Encoder
“Dual S/P Chk” (1) - 2 Encoders with Speed and Position Discrepancy Checking
“Dual Spd Chk” (2) - 2 Encoders with Speed Discrepancy Checking
“Dual Pos Chk” (3) - 2 Encoders with Position Discrepancy Checking Default:
Options: 0 = “Single Fbk”
0 = “Single Fbk”
1 = “Dual S/P Chk”
2 = “Dual Spd Chk”
3 = “Dual Pos Chk” RW 8-bit
Integer
28 Fbk 1 Type
Feedback 1 Type
Selects the type of feedback for encoder 1.
When using the Safe Speed Monitor module with a 20-750-UFB-1 Universal Feedback
module, set this parameter to 0 “Sine/Cosine” and ensure that the Universal Feedback
module is set to a Sine/Cosine type device (P6 [FB0 Device Sel] and/or P36 [FB1 Device
Sel]). Default:
Options: 1 = “Incremental”
0 = “Sine/Cosine”
1 = “Incremental” RW 8-bit
Integer
29 Fbk 1 Units
Feedback 1 Units
Selects rotary or linear feedback for encoder 1. Default:
Options: 0 = “Rev”
0 = “Rev” (Rotary)
1 = “mm” (Linear) RW 8-bit
Integer
30 Fbk 1 Polarity
Feedback 1 Polarity
Defines the direction polarity for encoder 1. Default:
Options: 0 = “Normal”
0 = “Normal” (Same as encoder)
1 = “Reversed” RW 8-bit
Integer
31 Fbk 1 Resolution
Feedback 1 Resolution
Counts/Revolution.
1…65,535 pulses/revolution or pulses/mm based on rotary or linear configuration
defined by P29 [Fbk 1 Units]. Default:
Min/Max: 1024
1 / 65535 RO 16-bit
Integer
32 Fbk 1 Volt Mon
Feedback 1 Voltage Monitor
Encoder 1 voltage to be monitored. Default:
Options: 0 = Voltage not monitored
0 = Voltage not monitored
5 = 5V +/- 5%
9 = 7…12V
12 = 12V +/- 5%
24 = 24V - 10%…24V + 5% RW 8-bit
Integer
33 Fbk 1 Speed
Feedback 1 Speed
Displays the output speed of encoder 1.

Integer
35 Fbk 2 Polarity
Feedback 2 Polarity
Defines the direction polarity for encoder 2. Default:
Options: 0 = “Normal”
0 = “Normal” (Same as encoder)
1 = “Reversed” RW 8-bit
Integer
