Direction of rotation:
715
1 = standard, position is counting positive when the drive is running forward.
-1 = position is counting negative when the drive is running forward.
2 = as "1", but with opposite sign of the reference to the drive. This can be used as
-2
used as alternative to swapping two motor phases if direction of motor rotation is wrong.
Maximum speed: Enter here the maximum speed of the slave drive, measured at the
716
slave encoder in revolutions per minute.
Minimum ramp: Enter here the minimum possible ramp in which the slave drive can
717
accelerate from 0 to the speed specified in Parameter 716. This is input in milliseconds.
Ramp type: Specify here the ramp type to be used.
718
0 = linear ramp
1 = sinusoidal ramp
Please note that a sinusoidal ramp requires a greater acceleration torque than a linear
ramp. On the other hand, a sinusoidal ramp produces less stress to the mechanics.
Maximum track error: Enter here the maximum track error. This is the permitted error
719
between the calculated position and the feedback position. If the value is exceeded, the
drive stops and displays the error message: O.ERR_8 "Position error". The value should
be set higher than the permitted tolerance range ACCURACY in Parameter 733. Input in
quad counts.
Reversing behaviour:
720
0 = means that the slave drive may always reverse, e.g. after overshooting the
1 = the slave drive may only reverse when the master is reversing.
2 = the slave drive may never reverse.
721 Slave marker type: Select here the type of marker signal for the slave drive:
0 = rising edge of the zero track
1 = falling edge of the zero track
2 = rising edge at I6
3 = falling edge at I6
NOTE:
This parameter is only used in marker synchronizing mode (parameter 725 = 2 or 5).
722 Marker interval at the slave: Enter here the interval between two markers at the slave
drive in quad counts. If this value is not known, it can be determined during the test run.
For procedure, see description in the section "Testing the incremental encoders" in the
packaging application example.
NOTE:
This parameter is only used in marker synchronizing mode (parameter 725 = 2 or 5).
