Programming and Parameters
266
Heidn Encdr Type
Configures the encoder type manually if the Endat type is not used.
• Bit 0 “Reserved” Automatically set after power-up. Do not change.
• Bit 1 “Not EnDat” Enables/Disables EnDat serial communications. Serial communications must be turned on for permanent magnet motors or if absolute position is
required. With EnDat serial communications enabled, bit 2 “Multi Turn” and the value of parameter 267 [Heidn Encdr PPR] will be automatically set on power-up.
• Bit 2 “Multi Turn” set to “1” (True) if the encoder supports mutli-turn absolute position. This bit is set automatically if bit 1 “Not EnDat” is set to “0” (False).
• Bit 5 “Endat24bitSl” when this bit is on, the Heidenhain encoder works as Endat / Single turn / 24 bits. When this bit is off, the Heidenhain encoder works as Endat / Single
turn / 20 bits.
• Bit 6 “VrtlMasterEn” when set, indicates that the Virtual Master encoder function of the Heidenhain option card is active. The Virtual Master function is available with v3.00
or later of the Heidenhain option card.
Notes: This parameter was added for firmware version 2.003. Bit 1 “Not Endat” was changed to “0” (false) and bit 2 “Multi Turn” was changed to “1” (true) for firmware version
2.004. Bit 1 “Not Endat” was changed to “1” (true), bit 2 “Multi Turn” was changed to “0” (False), and bit 6 “Endat24bitSl” was added for firmware version 3.001. Added bit 6 for
firmware version 4.001.

Heidn Encdr PPR
Set this value equal to the Heidenhain encoder PPR (e.g., 2048). This value is automatically set when bit 1
“NotEnDat” of parameter 266 [Heidn Encdr Type] is set to “0” (False).
Note: This parameter was added for firmware version 2.003. Changed the minimum value from “10” to “1” for
firmware version 4.001.
