The above four parameters are used for slave / ratioing of Speed / Position with respect to the Pulse reference input. The sampled pulse
counts per every 250µs are multiplied by the corresponding numerator and divided by the corresponding denominator to obtain the required
ratio of Speed / Position of the slave following the pulse reference input.
This parameter selects the ratio bank to be used for slave / ratioing.
0 - Selects the ratio bank-0 (Ratio numerator 0 & Ratio denominator 0)
1 - Selects the ratio bank-1 (Ratio numerator 1 & Ratio denominator 1)
Phase advance / retard of the slave axis
Three parameters allow phase advance or retard the slave axis. Pulse Reference Offset [13.29] parameter specifies the absolute offset angle
in encoder counts (65536 counts / rev). After setting the offset user enables the bit Move to Offset [13.30] to change the position. The drive
then moves to the new relative position with the programmed Maximum Rate of change [13.31] (Pulses/ 125µs). Drive clears 13.30 after
reaching to the new position.
The absolute offset angle in encoder counts (65535 counts / rev).
When this bit is set to 1, with a non-zero value of Pulse Reference Offset [13.29] the slave will move with the specified Maximum Rate of
change, by deducting the specified Maximum Rate of change from Pulse Reference Offset [13.29]every125µs, until Pulse Reference Offset
[13.29] becomes zero. This bit is cleared by the sequencer when Pulse Reference Offset [13.29] reaches zero.
The Maximum no of pulses that could be moved every 125µs.
