Step 2. Press the ENTER key repeatedly to advance through each of the monitor

mode LEDs. All of the monitor mode LEDs will then turn on at once and the
reference will be displayed. Note that the displayed speed reference value is
scaled based on P.028. The torque reference value is displayed in percent.

If the selected reference is negative and its value is greater than 999, the
SPEED LED will flash (refer to section 3.4.1, Display Range).

Pressing the ENTER key again advances you to the SPEED monitor display.

3.1.2 Entering the Manual Speed Reference

You can change the manual speed reference at any time while in monitor mode
regardless of the control source. Follow these steps to enter the manual speed
reference:

Step 1. From monitor mode, press the ▲

key or the ▼ key once. The monitor mode

LEDs all turn off, and the current manual speed reference value is displayed.

Step 2. Press the ▲

key or the ▼ key to change the displayed value to the desired

manual speed reference. Note that the speed reference is in the units
defined in P.028.

Important: The drive accepts the value as it is changed. You do not have to press the

ENTER key to save the value as you do with parameter entry.

Step 3. Press the ENTER key or wait approximately 5 seconds without pressing the

▲ or

▼ keys to return to monitor mode. (If the drive is not running, you must

press the ENTER key to return to monitor mode.)

Program Mode

Program mode allows you to display and modify drive parameter values. To enter
program mode, press the PROGRAM key until the PROGRAM LED turns on. The
following can be displayed in program mode:

Parameter numbers

Parameter values

Error log information

If the Programming Disable parameter (P.051) has been set to prevent parameter
modification from the keypad, the PASSWORD LED will also be on. In this case,
before any parameter values can be modified, the operator will have to access
parameter P.051 and enter the password (a factory-set value) to re-enable
programming. When programming has been enabled, the PASSWORD LED will turn
off.

Note that some of the parameters can be changed only when the drive is stopped.
Refer to chapter 4 for programming instructions and parameter descriptions.
