50 FB1 SSI Cfg
Feedback 1 SSI Configuration RW 16-bit
Integer
Configures the communication to a SSI encoder for the feedback 1 device. Transmission format: [MSB...Position...LSB], [Error Bit]*, [Parity Bit]*.
Bit 0 “Parity Bit” – If set, SSI encoder has to support a parity bit (even parity).
Bit 2 “Gray Code” – Enables the gray to binary conversion of the position.
Bit 3 “Err Bit Enbl” – If set, there is an error bit transmitted by the encoder.
Bit 4 “DblWordQuery” – If set, a Double Word Query is executed at startup which means that the same position is transmitted twice by the encoder. If the two
positions are not identical, the “Comm” error bit in [FB1 Sts] is set. This bit only needs to be cleared if the encoder does not support Double Word Query and it does
not send zeros instead of the second position (which it actually should according to the SSI specification).
51 FB1 SSI Resol
Feedback 1 SSI Resolution
Configures the number of bits for the position within one revolution (resolution) of the
SSI encoder for the feedback 1 device. Units:
Default:
Min/Max: Bits
13
8 / 32 RW 32-bit
Integer
52 FB1 SSI Turns
Feedback 1 SSI Turns
Configures the number of bits for the revolutions of the SSI encoder for the feedback 0
device. Setting is based on the encoder specifications. Set to 0 for a linear SSI encoder. Units:
Default:
Min/Max: Bits
12
0 / 16 RW 32-bit
Integer
55 FB1 Lin CPR
Feedback 1 Linear Encoder Counts Per Revolution
Specifies the counts per motor revolution for a linear encoder for the feedback 1 device. Default:
Min/Max: 0
0 / 4294967295 RW 32-bit
Integer
56 FB1 Lin Upd Rate
Feedback Linear Update Rate
Sets the sample rate for the linear channel for the feedback 1 device. Default:
Options: 2 = “1.5 ms”
0 = “0.5 ms”
1 = “1.0 ms”
2 = “1.5 ms”
3 = “2.0 ms” RW 32-bit
Integer
57 FB1 LinStahl Sts
Feedback 1 Linear Stahl Status RO 16-bit
Integer
Displays the error status of the linear Stahl encoder for the feedback 1 device.
Bit 0 “Optics Alarm” – Displays an alarm when fiber optics require cleaning.
Bit 1 “OutOfRailAlm” – Indicates that the read encoder count is at the maximum value (524,287).
Bit 4 “OutOfRailErr” – Indicates that there is no more room between the read head and the rail.
Bit 8 “Read Head 1” – Indicates that the read head must be cleaned or installed correctly.
Bit 9 “Read Head 2” – Indicates that the read head must be cleaned or installed correctly.
Bit 10 “RAM Error” – Indicates a RAM error. Reading head needs to be repaired.
Bit 11 “EPROM Error” – Indicates an EPROM error. Reading head needs to be repaired.
Bit 12 “ROM Error” – Indicates a ROM error. Reading head needs to be repaired.
Bit 14 “No Position” – Indicates that no position value was available. Only happens after power on or reset.
