Pid Deactivation By Digital Input; Pid Status Indication - Bosch rexroth EFC 610 Series Operating Instructions Manual

282/653
Functions and Parameters
Fig. 12-101: PID feedforward
The parameters E4.19 and E4.20 are both used for limiting the value of PID feed-
forward. E4.19 is the percentage relative to the main frequency, and E4.20 is the
percentage relative to E0.08.
So, the range of PID feedforward frequency is:
-Min{[E4.19] ╳ Main frequency + [E4.20] ╳ [E0.08], [E0.09]}...Min{[E4.19] ╳
Main frequency + [E4.20] ╳ [E0.08], [E0.09]}

PID Deactivation by Digital Input

The PID control is deactivated in the following ways:
'PID reference channel' [E4.00] = '0: No PID control' or
●
'X1...X4 input' [E1.00]...[E1.04] or 'EX1...EX4 input' [H8.00]...[H8.03] = '41:
●
PID deactivation' and respective multi-function digital input terminal is active.

PID Status Indication

[E4.32] 'PID engineering value detection width' is used to set the tolerance win-
dow between [d0.70] 'PID reference engineering value' and [d0.71] 'PID feed-
