Possible Solutions
Default
Recommended Setting
•
Increase torque at low speeds
•
Prevent shock during start up
E1-08 [Mid Point A Voltage]
•
If the torque is not sufficient at
low speeds, increase the setting
value.
•
If there is a large shock during
start up, decrease the setting
value.
15.0 V
13.0 V to 16.0 V
E1-10 [Minimum Output Voltage]
9.0 V
7.0 V to 10.0 V
*1
The default setting changes when the settings for
C6-01 [Normal / Heavy Duty Selection]
and
o2-04 [Drive Model (KVA) Selection]
change.
*2
The default setting changes when the settings for
A1-02 [Control Method Selection]
and
E1-03 [V/f Pattern Selection]
change.
*3
This is the setting for 200 V class drives. Multiply the voltage by 2 for 400 V class drives.
Open Loop Vector Control Method
Do not adjust parameter
C4-01 [Torque Compensation Gain]
. Keep this parameter at its default setting.
If you cannot get speed accuracy during regeneration, set
C3-04 = 1 [Slip Compensation at Regen = Enabled Above
6Hz]
. If you cannot get speed accuracy at high speeds, set
C3-05 = 1 [Output Voltage Limit Selection = Enabled]
.

increase the setting value.
20 ms
20 ms to 100 ms
•
Increase speed response
•
Increase speed stability

setting value.
1.0
0.5 - 1.5
•
Increasing motor excitation
sound
•
Prevent hunting and oscillation
at low-range speeds (10 Hz to
or lower)

at low speeds, decrease the
setting value.
1 - F
•
Increase torque and speed
response at low speeds
•
Prevent shock during start up
E1-08 [Mid Point A Voltage]
•
If the torque and speed response
are slow, increase the setting
value.
•

start up, decrease the setting
value.
11.0 V
12.0 V to 13.0 V
E1-10 [Minimum Output Voltage]
2.0 V
2.0 V to 3.0 V
*1
If the value for
C4-02 [Torque Compensation Delay Time]
is high, the current can increase during start up. Adjust and check the current
during start up.
*2
The default setting changes when the settings for
C6-01 [Normal / Heavy Duty Selection]
and
o2-04 [Drive Model (KVA) Selection]
change.
*3
This is the setting for 200 V class drives. Multiply the voltage by 2 for 400 V class drives.
