Chapter 5. DETAILED DESCRIPTION OF EACH FUNCTION
• When the control output type is R1 (motor drive relay output), the display and
setting can be performed. However, when [C57: Position proportional type] is
set at “2” (Estimated position control) or “3” (Estimated position c
Position adjustment at power ON), the display and setting cannot be performed.
• When using the motor auto adjust function of the position proportional control,
[C61: Input with motor fully closed], [C62: Input with motor fully open], and
[C63: Motor full close-full open time] are set automatically.
• Motor auto adjusting procedures
1. Set “0” or “1” to [C57: Position proportional type].
2. Set “1” to [C60: Motor auto adjust] and press the
[enter] key.
When this setup (C60) is already set at “1”, press the [enter] key twice.
3. The motor auto adjust is then started.
• The upper display shows and the relay on the close side is turned ON.
• The motor is moved toward the close side and the MFB count value is
shown on the lower display. When the counting becomes stable, the fully
closed adjustment is completed. This count value is then written into [C61:
Input with motor fully closed].
• The upper display shows and the relay on the open side is turned ON.
• The motor is moved toward the open side and the MFB count value is shown
on the lower display. When the counting becomes stable, the fully open
adjustment is completed. This count value is then written into [C62: Input
with motor fully open]. Additionally, a period of time, which has elapsed
from the fully closed position to the fully open position, is written into [C63:
Motor full close-full open time]. However, if this time is 240.0s or longer,
“240.0s” is set to this parameter.
• When the motor auto adjust has been completed, the basic display screen
will appear.
4. To cancel the adjustment, press the [display] key.
When the motor auto adjust is started, keys other than the [display] key used
to cancel the adjustment cannot be operated.
If any of the following arises, each value is returned to its default setting
before shipment and “AL10” is shown as the troubleshooting process.
“AL10” is cleared only when the motor auto adjust is restarted and completed
correctly or when the power is reset.
• The count value between the fully closed position and fully open position is
less than “260”.
• The fully closed count is greater than the fully open count.
• The period of time from the fully closed position to the fully open position is
less than 5s.
• The MFB burnout alarm (AL07) is continued or occurs frequently.
• The period of time that the MFB count value becomes stable exceeds 5min.
• The MFB or open/close relay has faulty wiring.
(However, all of faulty wiring cannot be detected as error.)
• As the data is written into the motor auto adjust (decimal address: 5260) through
the CPL or MODBUS communication, the starting of the motor auto adjust can
be cancelled. To start the motor auto adjust, “1” is written. On the contrary, to
cancel the motor auto adjust, “0” is written.
Handling Precautions
• If the power to the measuring instrument is turned OFF during motor
auto adjust of the position proportional control, the motor auto adjust
is cancelled when the power is turned ON again.
• Even though the AUTO/MANUAL mode, RUN/READY mode, or
LSP/RSP is changed during motor auto adjust, the motor auto adjust
is continued.
