SIEPCYEUOQ2V01A Q2V Technical Manual
Stall prevention during acceleration prevents the stalling and stopping of motors when
oC [Overcurrent]
,
oL2
[Drive Overloaded]
, or
oL1 [Motor Overload]
is detected in cases of significant loads applied during acceleration
or sudden acceleration times regarding load inertia are set.
1 : Disabled
The Stall Prevention function does not operate during acceleration, and acceleration occurs for the set acceleration
time. If the acceleration time is too short, the motor will not fully accelerate during the set time, which causes the
drive to detect
oL1
or
oL2
and the motor to stop.
2 : General Purpose
Enables the Stall Prevention During Acceleration function. Operation is different for different control methods.
•
V/f Control, Open Loop Vector Control, or EZ Open Loop Vector Control
When the output current is more than the value set in
L3-02 [StallP Level@Accel]
, the drive stops acceleration.
Deceleration is stopped once the output current falls below the value set in
L3-02
- 15%. The Stall Prevention
function level automatically falls for constant output ranges.
Figure 12.116 Stall Prevention During Acceleration when Using Induction Motors
•
Open Loop Vector Control for PM
When the output current is more than the value set in
L3-02
, the drive stops acceleration. When the time set in
L3-27 [StallP Detect Time]
is expired and the output current is larger than in
L3-02
, the drive will start
deceleration in as specified by
L3-22 [StallP@Acc Deceleration Time]
. The drive starts acceleration again once
the output current falls below the value set in
L3-02
- 15%. When the time set in
L3-27
is expired, the drive
starts acceleration again.
Figure 12.117 Stall Prevention During Acceleration Function in OLV/PM
3 : Intelligent Accel
The drive ignores the acceleration time setting and the drive starts to accelerate in the minimum length of time.
The drive automatically adjusts the acceleration rate to make sure that the output current is not more than
L3-02
.
