Error Reading Data
You tried to back up the data when
o3-02 = 0 [Copy
Allowed Selection = Disabled]
.
Set
o3-02 = 1 [Enabled]
and back up again.
vAEr
Voltage Class, Capacity Mismatch
The power supply specifications or drive capacity
parameter settings are different between the keypad
and the drive.
1.
Make sure that drive model and the value set in
o2-04 [Drive
Model (KVA) Selection]
agree.
2.
Restore the parameters.
vFyE
Parameters do not Match
The parameters that are backed up in the keypad
and the parameters in the drive are not the same.
1.
Restore or backup the parameter again.
2.
Verify the parameters.

Accel & Decel Time
0.0 s to 6000.0 s
The drive allows four selectable combinations of independent acceleration and deceleration settings.
Braking Torque
Approx. 20%
Approx. 125% with a dynamic braking option
•
Short-time average deceleration torque
Motor output 0.4/0.75 kW: over 100%
Motor output 1.5 kW: over 50%
Motor output 2.2 kW and larger: over 20%, approximately 40% with overexcitation braking
•
Continuous regenerative torque: Approx. 20%. Dynamic braking option allows for approximately 125%, 10% ED, 10 s
Note:
•
Models 2003 to 2115 and 4002 to 4150 have a braking transistor.
•
Set
L3-04 = 0 [Stall Prevention during Decel = Disabled]
when using a regenerative converter, regenerative unit, braking unit, braking resistor, or
braking resistor unit. The drive may not stop within the designated deceleration time if
L3-04 = 0
.
•
Short-time average deceleration torque refers to the torque required to decelerate the motor (uncoupled from the load) from the rated speed to zero.
Actual specifications may vary depending on motor characteristics.
•
Continuous regenerative torque and short-time average deceleration torque for motors 2.2 kW and larger vary depending on motor characteristics.
