Chapter 2 Programming and Parameters
259 Stegmann0 Cnfg
Configures the Stegmann Hi-Resolution Encoder Feedback Option.
• Bit 5 “Direction” determines counting direction. If clear, direction is forward or up. If set, the direction is reverse or down.
• Bits 10 “SmplRate bt0” -12 “SmplRate bt2” configure the Finite Impulse Response (FIR) Filter (see
Table 259A: FIR Filter Settings ). This setting reduces the effect of noisy feedback on the system.
Refer to the Speed/Position Feedback section of the PowerFlex® 700S with Phase II Control Reference Manual, publication PFLEX-RM003 for details.
Notes: Bit 11 “SmplRate bt1” is set to 0 = False by default for firmware version 1.11 and is set to 1 = True by default for firmware version 2.003. This parameter was changed to non-linkable for
firmware version 3.001.
260 Stegmann0 Status
Indicates faults on the Stegmann Hi-Resolution Encoder Feedback Option.
• Bit 8 “Open Wire” indicates an open wire fault.
The feedback option card checks for a pre-determined constant value. If this value is not within tolerances, an open wire fault is declared. A quadrature check also is done. If an error occurs during
the check, the ope wire check is aborted. If 3 quadrature errors occur in succession, the open wire check will complete and the constant value checked again. If this value is not within tolerances,
the fault is declared.
• Bit 9 “PowerSup Er” indicates the failure of the power supply.
• Bit 10 “PwrUpDiag Er” indicates the option board failed its power-up diagnostic test.
The pattern on the FPGA must be identical to the pattern written from the DSP, or the board status test will fail.
• Bit 11 “MsgChksum Er” indicates a message checksum fault.
The check sum associated with the Heidenhain encoder must be correct and acknowledged by the feedback option card.
• Bit 12 “Time Out Err” indicates a RS-485 time-out fault.
This check requires information to be sent from the encoder to the feedback option card within a specified time. Typical times are about 10 clock cycles before an error is detected. This check is
done only at power-up.
261 Steg&Hiedn TPSel
Selects data displayed by Par 262 [Steg&Hiedn TPDta].
• Hh0 Edge Time - Latency counter value, not used for Hi-Resolution Feedback Option.
• Hh0 dEdge - Change in edge counts for one 500 microsecond update. At constant speed, this value should be
constant.
• Hh0 dTime - Change in update time. This value should be constant, 500 microseconds.
• Hh0 EPR - This value should be 1,048,576 counts per revolution-this is a constant value.
• Hh0 nMax - This is a scaled value of 2.
• Hho Delta2Err - Derivative of value 2.
