* 1. The setting ranges 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 setting depends on the Drive capacity.
* 3. These are values for a 200-240V class Drive. Values for a 380-480V class Drive are double.
* 4. The factory setting will change when the control method is changed. (Open-loop vector 1 factory settings are given.)
* 5. After autotuning, E1-13 will contain the same value as E1-05.
* 6. The factory setting depends on the Drive capacity. (The value for a 200-240V Class Drive for 0.4 kW is given.)
* 7. The setting range is from 10% to 200% of the Drive rated output current. (The value for a 200-240V Class Drive for 0.4 kW is given.)
* 8. L3-04 cannot be set to 3 for flux vector control or open-loop vector control 2.
* 9. The setting range is 0 to 66.0 for open-loop vector control 2. The upper limit for the setting range also depends on the upper limit in E1-04.
The maximum setting is 400.00.
* 10.The same capacity as the Drive will be set by initializing the parameters.
* 11.The setting range is 0 to 2 for flux vector control and open-loop vector control 2.
* 12.Quick Settings are used if Multi-Function Input is set for two motors.
* 13.Setting range changes to {1,2} when operating in Flux Vector and in Open Loop Vector.

During
Deceleration When using a braking resistor, use
setting "0". Setting "3" is used in
specific applications.
0: Disabled - The Drive decelerates at
the active deceleration rate. If the
load is too large or the deceleration
time is too short, an OV fault may
occur.
1: General Purpose - The Drive
decelerates at the active
deceleration rate, but if the main
circuit DC bus voltage reaches the
stall prevention level (380/760Vdc),
deceleration will stop. Deceleration
will continue once the DC bus level
drops below the stall prevention
level.
2: Intelligent - The active deceleration
rate is ignored and the Drive
decelerates as fast as possible w/o
hitting OV fault level. Range:
C1-02 / 10.
3: Stall Prevention w/ Braking Resistor -
Stall prevention during
deceleration is enabled in
coordination with dynamic braking.
