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.

P47 CLEAR FAULT HISTORY

01 MAINTAIN: Maintains the FAULT HISTORY (Parameter 50) entries for

troubleshooting.

02 CLEAR: Erases the FAULT HISTORY (Parameter 50) entries.
