Rate Control Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Rate Control Function

The increment/decrement of the analog output value per 80s is restricted to prevent the sudden change of the analog output
value.
When the inter-module synchronization function is enabled, the rate control function cannot be used.
Operation
When the change amount of 'CH1 Digital value' (Un\G460) is larger than the value set in 'CH1 Increase digital limit value'
(Un\G514) or 'CH1 Decrease digital limit value' (Un\G516), this function changes 'CH1 Digital value' (Un\G460) by the limit
values set for each digital limit value.
The increment/decrement values per 80s are set for 'CH1 Increase digital limit value' (Un\G514) and 'CH1 Decrease digital
limit value' (Un\G516). However, the actual update cycle of the output value of the corresponding channel is (80s  Number
of conversion-enabled channels).
Therefore, the analog output value increases or decreases per update cycle as follows:
First time: The D/A conversion value of the increase/decrease digital limit value
Second time or later: The D/A conversion value of (Increase/decrease digital limit value  Number of conversion-enabled
channels)
