Virtual Encoder Output to the Heidenhain Option Card

With firmware version 4.001 you can program the Heidenhain feedback option
for a scalable virtual encoder output. The virtual encoder output can be taken
from the speed reference section or linked to other feedback parameters and be
scaled to the desired EPR. The following parameters provide this functionality.

• Bit 7 “VM Direction” of parameter 263 [Heidenhain0 Cnfg]
• Bits 0 “VM Enc Out” and 1 “Emul Enc Out” of parameter 264

[Heidenhain0 Stat]

• Bit 6 “VrtlMasterEn” of parameter 266 [Heidn Encdr Type]
• Parameter 267 [Heidn Encdr PPR] with a minimum value of “1”.
• Bit 7 “EGR Enable” of parameter 1000 [UserFunct Enable]
• Parameter 1160 [VirtEncPositFast]
• Parameter 1161 [EGR Config]
• Parameter 1162 [EGR Mul]
• Parameter 1163 [EGR Div]
• Parameter 1164 [EGR Pos Input] (only linkable to Pars 250 [FB Opt0

Posit], 762 [Position Fdbk], and 1160 [VirtEncPositFast])

• Parameter 1165 [EGR Pos Output]
• Parameter 1166 [EGR Pos Preset]
