Set the number of multiples of 10 V to
be output as the 100% output for the
H4-05
monitor items. Voltage output from the
端子 AM 增
terminals, however, have a 10 V max.

able.
Motor pro- Set to enable or disable the motor
tection overload protection function using the
selection electronic thermal relay.
0: Disabled
1: General-purpose motor protection
2: Inverter motor protection
3: Vector motor protection
In some applications when the
L1-01
Inverter power supply is turned off,
电机保护功
the thermal value is reset, so even if
能选择
this constant is set to 1, protection
may not be effective.
When several motors are connected to
one Inverter, set to 0 and ensure that
each motor is installed with a protec-
tion device.
Stall pre- 0: Disabled (Deceleration as set. If
vention deceleration time is too short, a
selection main circuit overvoltage may
during result.)
decelera- 1: Enabled (Deceleration is stopped
tion when the main circuit voltage
exceeds the overvoltage level.
Deceleration restarts when voltage
is returned.)
2: Intelligent deceleration mode
L3-04
(Deceleration rate is automatically
adjusted so that the Inverter can
decelerate in the shortest possible
减速防止失
time. Set deceleration time is
速选择
disregarded.)
3: Enabled (with Braking Resistor
Unit)
When a braking option (Braking
Resistor, Braking Resistor Unit, Brak-
ing Unit) is used, always set to 0 or 3.
* 1. The setting range for acceleration/deceleration times depends on the setting of C1-10 (Acceleration/deceleration Time Setting Unit). If C1-10 is set to 0,
the setting range is 0.00 to 600.00 (s).
* 2. The factory settings depend on the Inverter capacity. The values for a 200 V Class Inverter for 0.4 kW are given.
* 3. These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
* 4. The factory setting will change when the control method is changed. The open-loop vector 1 factory settings are given.
* 5. E1-13 is set to the same value as E1-05 by autotuning.
* 6. The setting range is from 10% to 200% of the Inverter rated output current. The value for a 200 V Class Inverter for 0.4 kW is given.
For the motor no-load current, set E2-03 to a value less than that of E2-01.
* 7. The setting range for open-loop vector 2 control is 0 to 132.0.
* 8. The same capacity as that of the Inverter will be set if the constants are initialized.
* 9. The setting range for flux vector and open-loop vector 2 control is 0 to 2.
* 10.0 or 1 for flux vector control and open-loop vector 2 control.
* 11.The setting range depends on the capacity of the Inverter. The values for a 200 V Class Inverter for 0.4 kW are given.
* 12.Displayed in Quick Programming Mode when motor 2 is set for a multi-function input.
* 13.The CH1 output can be adjusted when the H4-02 or H4-03 setting is displayed in Quick, Advanced, or Verify mode while the motor is stopped.
The CH2 output can be adjusted when the H4-05 or H4-06 setting is displayed in quick, Advance, or Verify mode while the motor is stopped.
For analog output, the value equivalent to 100% of output value of monitored item is multiplied by the gain setting and the set bias is added.
