Standard screens are indicated by a solid line box
and optional
screens are indicated by a dotted line box
.
Optional screens may not be displayed depending on the product specifications.
0. Monitor screen group
Screen group that displays data such as voltage, current and input values of various loads
0-0. Output monitor (basic screen)
Basic screen for the device.
Displays current output.
When phase control (phase angle proportional control) is selected: Output phase angle (%)
When phase control (voltage proportional control) is selected:
Output voltage (%)
When phase control (voltage square proportional control) is selected: Output power (%)
When cycle calculation zero voltage switching control is selected: Output operation amount (%)
When complex control is selected:
Output operation amount (%)
Switches from this screen to various parameter groups for checking/setting
various parameter settings.
range: 0.0 – 100%
(fractional digits below decimal point not displayed for 100%)
Switches to subsequent screen

0-1. Load current (optional)
Displays load current value (A).
Range: At least 5% of rated current
(Fractional digits below decimal point not displayed for 100 A or more)
Displayed when current is below 5% of the rating.
0-2. Control input
Displays control input value.
Controls according to power supply frequency, so it can’t handle faster variation.
range: -10.0 – 110%
(fractional digits below decimal point not displayed for 100% or more)
or
is displayed if control input is less than -10%;
is
displayed if 110% is exceeded. Differs according to type of control input.
If set to contact 2-position control (on/off control),
is displayed for
C3-C2 terminal short and
is displayed for C3-C2 terminal open.
0-3. VR1 operation amount
Operation amount of VR1 is displayed in the range of 0 – 100%.
Set either key sequence ‘1-7. Ramp lower limit setting, ’
key sequence ‘1-8.
Ramp higher limit option,’ or key sequence ‘1-11. Current limiter.’
range: 0.0 – 100%
(fractional digits below decimal point not displayed for 100%)
0-4. VR2 operation amount
Operation amount of VR2 is displayed in the range of 0 – 100%.
Set either key sequence ‘1-7. Ramp lower limit setting, ’ key sequence ‘1-8.
Ramp higher limit option,’ or key sequence ‘1-11. Current limiter.’
range: 0.0 – 100%
(fractional digits below decimal point not displayed for 100%)
0-5. VR3 operation amount

VR3 is used for manual operation.
range: 0.0 – 100%
(fractional digits below decimal point not displayed for 100%)
Switches to key sequence ‘0-0. Basic screen.’
1. User parameter screen group
The user can modify the control operation parameters.
You can obtain safer, more reliable control characteristics by various type
of alarm output settings and settings such as overcurrent limit.
The user parameter screen group is accessed by pressing and holding
for at least 1.5 seconds from key sequence ‘0-0. Output monitor (basic screen).’
Switches parameters.
Enters selection.
1-0 User parameter screen
Displays the initial screen of the user parameter screen group.
Switch to this screen when returning to the basic screen from the user
parameter screen group.
Switches to subsequent screen

key sequence ‘1-1’
1-1. Key lock
Limits operation of parameters screens.
Initial value:
：
User screen group other than key lock and
initial screen group operation disabled
：
All parameter screen operation enabled

1-2. Complex control phase angle adjustment
(enabled when complex control selected)
This screen is displayed when complex control is selected as a product
specification.
May produce delay in current phase due to load and transformer used.
This could upset magnetic balance of the transformer, cause the transformer
to become saturated, and excessive current could flow. This can be avoided
by adjusting to eliminate current imbalance. Adjust while monitoring the
waveform of the transformer load current with an oscilloscope, etc., using an
actual load. See ‘16-6. Complex control phase angle adjustment.’
Initial value: 10.0
Range: 0.0 – 30.0
Entered by
1-3. Power failure error alarm (optional)
Sets whether or not to output an alarm when a power failure occurs.
Initial value:
：
Allotted to alarm output 1
：
Alarm not output
Entered by
1-4. Overcurrent error alarm (optional)
Sets whether or not to output an alarm when overcurrent protection circuit
is triggered.
Initial value:
：
Allotted to alarm output 1
：
Alarm not output
