Parameter Descriptions
27-70 Relay
27-70 Relay is an array parameter used to setup the function of
the option relays. Depending on which option is installed only
the available relays will be visible. If Extended Cascade Controller
is installed, relay 10-12 will be visible. If Advanced Cascade
Controller is installed relay 13-20 will be visible. In both cases,
the standard relays (Relay1 and Relay2) will be accessible as well
as the relays in the B-option MCB 105 (if that option is installed
in combination with advanced cascade).
To setup the function of each relay, choose the specific relays
and then choose the function. If the function option: Standard
Relay is choosen, the relay can be used as general purpose relay
and the wanted function can then be setup in parameter group
5-4* Relays.

Cascade Control Option Readout Parameters
27-91 Cascade Reference
Cascade Reference is a readout parameter that shows the
reference output for use with follower drives. This reference is
available even when the master drive is stopped. This is the
speed that the frequency converter is operating at or would be
operating at if it were on. It is scaled as a percent of Motor Speed
High Limit (4-13 Motor Speed High Limit [RPM] or 4-14 Motor Speed
High Limit [Hz]).

27-92 % Of Total Capacity
Current % of Total Capacity is a readout parameter that shows
the system operating point as a % capacity of total system
capacity. 100% means all pumps are on at full speed.
