xx286 Ch1 SC Amplitude Configurable P39
[FB1 Loss Cfg]
Indicates that the encoder 1 signal amplitude is out of tolerance.
xx287 Ch1 Open Wire Configurable P39
[FB1 Loss Cfg]
Indicates that an open wire condition has been detected for encoder 1.
xx288 Ch1 Quad Loss Configurable P39
[FB1 Loss Cfg]
Indicates that a signal quadrature error has been detected for encoder 1
xx289 Ch1 Phase Loss Configurable P39
[FB1 Loss Cfg]
Indicates that an A or B signal of an A quad B incremental encoder on
Channel 1 is disconnected.
xx290 Ch1 Unsupp Enc Configurable P39
[FB1 Loss Cfg]
Indicates that the connected encoder on Channel 1 is not supported
xx300 Ch1 FreqExc Alm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by Heidenhain Encoder on Channel 1 with EnDat
Interface - Frequency exceeded warning
xx301 Ch1 TempExc Alm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by Heidenhain Encoder on Channel 1 with EnDat
Interface - Temperature exceeded warning
xx302 Ch1 LightLim Alm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by Heidenhain Encoder on Channel 1 with EnDat
Interface - Limit of light control reserve reached
xx303 Ch1 Battery Alm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by Heidenhain Encoder on Channel 1 with EnDat
Interface - Battery warning
xx304 Ch1 RefPoint Alm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by Heidenhain Encoder on Channel 1 with EnDat
Interface - Reference point not reached
xx308 Ch1 General Alm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by an Encoder on Channel 1 with BiSS Interface - A
warning bit of the BiSS Single Cycle Data is set
xx315 Ch1 Optics Alarm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by a linear Stahl encoder on Channel 1 - Displays an
alarm when the Stahl optical system requires cleaning
xx316 Ch1 OutOfRailAlm Alarm 1 P39
[FB1 Loss Cfg]
Alarm reported by a linear Stahl encoder on Channel 1 - Indicates that
the read encoder count is at the maximum value (524287)
xx412 Hardware Err Configurable Either
P9 [FB0 Loss Cfg] or P39
[FB1 Loss Cfg]
Indicates that there is a Hardware Error on the Feedback Option module.
xx413 Firmware Err Configurable Either
P9 [FB0 Loss Cfg] or P39
[FB1 Loss Cfg]
Indicates that there is a Firmware Error on the Feedback Option module.
A Firmware Error occurs if the Hardware and the downloaded Firmware
are not compatible.
This error could also indicate that communication between the
Feedback Option module and the Main Control Board was interrupted
during power-up. Cycle power to clear this fault.
xx416 EncOut Cflct Alarm 1 Either
P9 [FB0 Loss Cfg] or P39
[FB1 Loss Cfg]
Indicates that there is one of the following problems with the Encoder
Output:
• The selection in the P80 [Enc Out Sel] is not possible since the
required pins on the terminal blocks are already used for Feedback 0
or 1 according to P6 [FB0 Device Sel] and P36 [FB1 Device Sel].
• P80 [Enc Out Sel] is set to 2 “Sine Cosine” and there is no signal
connected to the pins 1…4 of TB 1.
• P80 [Enc Out Sel] is set to 2 “Sine Cosine,” the value of P15/45 [FBX
IncAndSC PPR] is not a power of two, and P84 [EncOut Z PPR] is not
set to 0 “1 ZPulse.” The value of P15/45 [FBX IncAndSC PPR] must be
a power of two.
• P80 [Enc Out Sel] is set to 3 “Channel X” or 4 “Channel Y” and there is
no encoder connected to that channel.
• P80 [Enc Out Sel] is set to 3 “Channel X” or 4 “Channel Y” and there is
a linear encoder connected to this channel.
