P44 PASSWORD
This allows the PASSWORD to be changed to any number between 000 and 999 . Setting
PASSWORD to 000 disables the password function .
NOTE
The factory default password is 225 .
P45 SPEED AT MIN SIGNAL
This sets the speed at which the drive will run when it receives the minimum speed reference
signal (0 VDC or 4 mA) . This is used in conjunction with SPEED AT MAX SIGNAL (Parameter
46) to define the speed range of the drive when following an analog speed reference signal .
NOTE
When the drive is configured for -10 to +10 VDC speed control, SPEED AT
MIN SIGNAL will set the maximum speed that the drive will run at in reverse
direction when it receives -10 VDC . Refer to Parameter 07 - BIPOLAR
REFERENCE SELECTION .
P46 SPEED AT MAX SIGNAL
This sets the speed at which the drive will run when it receives the maximum speed reference
signal (10 VDC or 20 mA) . This is used in conjunction with SPEED AT MIN SIGNAL (Parameter
45) to define the speed range of the drive when following an analog speed reference signal .
NOTE
If SPEED AT MIN SIGNAL is set higher than SPEED AT MAX SIGNAL, the
drive will react inversely to the speed reference signal . Therefore, as the speed
reference signal increases, the drive speed will decrease, and vice-versa . This
function is disabled when using a -10 to +10 VDC speed reference signal . Refer
to Parameter 07 - BIPOLAR REFERENCE SELECTION .
