In the remote SP mode, the remote SP can be monitored on the No.2 dis
play for PV/SP . In the local SP mode, the remote SP can be monitored in

When the local SP is switched to from the remote SP when the SP track
ing function is enabled, the local SP is changed so that the remote SP
value is held at the SP value used immediately before switching.
To use the SP tracking function, set the SP tracking" parameter to
ON".
The following figure shows how SP tracking works when the SP mode
is switched.
