Parameter 10-00 and 10-01 cannot be set to the same source. If both parameters are set to the same
source the keypad will show a SE05 alarm.

PID Frequency Command
When 10-03= xxx1b
: PID is enabled, LCD keypad will be switched automatically (16-00) and main screen
monitoring displays PID target value (12-38). Sub-screen monitoring 1 (16-01) displays PID feedback value
(12-39) and sub-screen monitoring 2 (16-02) displays frequency output (12-17). If PID is disabled, the keypad will
switch automatically to frequency command setting as the main page.
When 10-03= xx1xb
: PID output is reverse. PID output is chosen to reverse, and if PID input is
negative
, the
output frequency of PID will gain.
On the contrary, PID output is chosen to forward, and if PID input is minus, the
output frequency of PID will decrease.
Refer to Fig. 4.4.78 & 4.4.79 when
10-03= x1xxb
: feedback value differential of PID control and
10-03= x0xxb:
basic PID control
When 10-03= 0xxxb
: PID output, it corresponds 100% to the frequency of 01-02.
When 10-03= 1xxxb
: PID
frequency command, it will cumulate the output percentage of frequency command, (corresponding to
01-02 main frequency command set by parameter 00-05/ 00-06) at the beginning of running and then start PID
control.
