CAM SCALE function

Function block for MP2000 series

<CAMSCALE> Function Block Summary

The Cam Scale “CAMSCALE” block is used to scale the value of the Cam table output during camming.

The rising edge of the EXECUTE input bit will cause the OFFSET value to be added to the RDA offset at

the rate determined by the DURATION input. DST-TIME input bit determines whether the shift duration is

base upon distance the master travels or based on time in milliseconds.1 = 0.01% for scaling.

<CAMSCALE> Function Block Operation Notes

• IMPORTANT NOTE: If the CamScale value in the RDA (ML56**8) is zero the

slave will not move.

• Rising edge of EXECUTE input initiates block operation, and all block input

values are read once.

• To use the function block, the EXECUTE bit must be held ON. If the EXECUTE

bit goes off during operation, the block will stop executing (will not complete the

change), the offset (or relative scale change) up to that point will remain, and all

outputs will be set to zero.

• The RUNNING output bit will be held high until the Offset (or relative scale

change) is completed, EXECUTE goes low, or an Error occurs.

• The DST-TIME bit must be set to TRUE to use the master position change or

FALSE for the time duration.
