Measuring gear configuration (p0411)
The following points can be set by configuring this parameter:
● p0411.0: Measuring gear, activate position tracking
● p0411.1: Setting the axis type (linear axis or rotary axis)
Here, a rotary axis refers to a modulo axis (modulo offset can be activated through
higher-level control or EPOS). With a linear axis, position tracking is mainly used to
extend the position area (see section: Virtual multiturn encoder (p0412)).
● p0411.2: Reset measuring gear position
Overflows can be reset with this. This is required, for example, if the encoder is rotated by
more than 1/2 the encoder range while switched off.
● p0411.3: Activate measuring gear position tracking for an incremental encoder
When position tracking is activated, for an incremental encoder only the actual position
value is stored. Movement by an axis / encoder when the system is switched off is not
detected! A tolerance window setting in p0413 has no effect.
Virtual multiturn encoder (p0412)
With a rotary absolute encoder (p0404.1 = 1) with activated position tracking (p0411.0 = 1),
p0412 can be used to enter a virtual multiturn resolution. This enables you to generate a
virtual multiturn encoder value (r0483) from a singleturn encoder. It must be possible to
display the virtual encoder range via r0483.
Note
If the gear factor is not equal to 1, then p0412 always refers to the motor side. The virtual
resolution, which is required for the motor, is then used here.
For rotary axes with modulo offset, the virtual multiturn resolution (p0412) is preset as p0421
and can be changed.
For linear axes, the virtual multiturn resolution (p0412) is preset as p0421 and extended by 6
bits for multiturn information (max. overflows 31 positive/negative)
If, as a result of extension of the multiturn information, the displayable area of r0483 (2
is exceeded, the fine resolution (p0419) must be reduced accordingly.
