Function Key Mode; Disable Auto-Reset On Enable - Emerson 2202 Advanced User's Manual

Parameter Parameter
Introduction
x.00 description format
1. Run forward, Run reverse and Run sequencing bits all zero
2. OR the drive is disabled via Pr 6.15 or Pr 6.29
3. OR Run forward and Run reverse are both active and have been for 60ms.
The drive can then be restarted by activating the necessary bits to give a normal start. This means that the drive cannot restart automatically after a
trip, for example, by pressing the stop key.
Sequencer latching enabled (Pr 6.40 = On)
If the stop key is pressed when the stop key is enabled (Pr 6.12 = On) or when the drive is tripped the sequencer run is removed, and so the drive
stops or remains stopped respectively. The sequencer run can only then be reapplied after at least one of the following conditions occurs.
1. Run forward, Run reverse and Run sequencing bits all zero after the latches
2. OR /Stop sequencing bit is zero
3. OR the drive is disabled via Pr 6.15 or Pr 6.29
4. OR Run forward and Run reverse are both active and have been for 60ms.
The drive can then be restarted by activating the necessary bits to give a normal start. This means that the drive cannot restart automatically after a
trip, for example, by pressing the stop key. Note that Run forward and Run reverse together will reset the stop key condition, but the latches
associated with Run forward and Run reverse must then be reset before the drive can be restarted.

Modes:
0. No function (Function key disabled)
1. Forward / Reverse toggle (keypad mode).
Pressing the Function key will toggle between the forward and reverse direction of the motor.
2. Run reverse
Pressing the Function key will run the drive in the reverse direction, the start button will run the drive in the forward direction.
3. Jog
Pressing the Function key will jog the drive. As with the normal jog function the drive needs to be stopped for the jog function to operate. Giving
the drive a start command when jogging will cause the motor to run at the speed reference selected in menu 1.
4. Auto
On power up of the Keypad Remote, Stop (off) mode is assumed. The following modes are entered with the appropriate key press in each mode.
Stop Mode
(Off) - LED Flashes
Stop

The Function key LED flashes to indicate waiting for a user action in Stop (off) mode and Keypad (Hand) mode .
The Function key LED stays on when in Terminal (Auto) mode.
5. User defined function
In this mode no function is assigned to the Function key, this mode allows the user to define their own function. This would normally be done through
a user program in a LogicStick using Pr 6.11 to monitor key presses (Pr 6.11 = state of Function key).
On the LCD keypad:
This parameter enables the Fwd/Rev key to operate in keypad mode.
6. Forward/ Reverse toggle
NOTE
If the serial comms is lost to the keypad i.e. SCL trip, the drive will need to be power cycled. This is to ensure that the drive operates correctly.
