Chapter 1 Detailed Drive Operation
Examples:
1. A Quad B output of Heidenhain feedback 2048 PPR from each rotation
of the virtual encoder.
• Set parameter 61 [Virt Encoder EPR] = 1048576
• Link parameter 1155 [Heidn VM Pos Ref ] to parameter 1160
[VirtEncPositFast]
• Set parameter 266 [Heidn Encdr Type], bit 6 “VrtlMasterEn” = 1
• Set parameter 1156 [Heidn VM Enc PPR] = 2048
2. A Quad B output of Heidenhain feedback 2048 PPR from each rotation
of Encoder0 input.
• Set parameter 1000 [UserFunct Enable], bit 7 “EGR Enable” = 1
• Link parameter 1164 [EGR Pos Input] to parameter 762 [Position
Fdbk]
• Set parameter 1161 [EGR Config], bit 0 = 1
• Set parameter 1162 [EGR Mul] = 256
• Set parameter 1163 [EGR Div] = 1
• Link parameter 1155 [Heidn VM Pos Ref ] to parameter 1165 [EGR
Pos Output]
• Set parameter 266 [Heidn Encdr Type], bit 6 “VrtlMasterEn” = 1
• Set parameter 1156 [Heidn VM Enc PPR] = 2048
Motor Speed Feedback and Scaled Speed Feedback
The motor speed feedback is selected according to the feedback device selection.
The value for motor speed feedback appears in parameter 300 [Motor Spd Fdbk].
The speed feedback enters the speed regulation loop from [Motor Spd Fdbk].
The filter for the speed feedback is shown in the speed regulation loop section.
A low pass filter branches off of the motor speed feedback. This low pass filter
filters out high frequency before displaying the speed feedback on the HIM.
