2.3 b: Application
Note:
When A1-02 = 5 or 8 [Control Method Selection = OLV/PM or EZOLV], the setting range is 0, 1, 3.
Select the applicable stopping method for the application from these four options:
0 : Ramp to Stop
When you enter the Stop command or turn OFF the Run command, the drive ramps the motor to stop.
The drive ramps the motor to stop as specified by the deceleration time. The default setting for the deceleration time
is C1-02 [Deceleration Time 1]. The actual deceleration time changes as the load conditions change (for example,
mechanical loss and inertia).
If the output frequency is less than or equal to the value set in b2-01 [DC Injection/Zero SpeedThreshold] during
deceleration, the drive will do DC Injection Braking or Short Circuit Braking as specified by the control method.
• Ramp to Stop with V/f Control Method
Parameter b2-01 sets the frequency to start DC Injection Braking at stop. If the output frequency is less than or
equal to the value set in b2-01 during deceleration, the drive will do DC Injection Braking for the time set in b2-04
[DC Inject Braking Time at Stop].
b2-01:
b2-04:
Note:
When b2-01 ≤ E1-09 [Minimum Output Frequency], the drive will start DC Injection Braking from the frequency set in E1-09.
• Ramp to Stop with OLV/PM and EZOLV Control Methods
Parameter b2-01 sets the frequency to start Short Circuit Braking. When the output frequency is less than or equal
to the value set in b2-01 during deceleration, the drive will do Short Circuit Braking for the time set in b2-13 [Short
Circuit Brake Time @ Stop]. When b2-04 ≠ 0, the drive will do DC Injection Braking for the time set in b2-04 when
Short Circuit Braking is complete.
b2-01:
b2-04:
Note:
When b2-01 ≤ E1-09, the drive will start Short Circuit Braking from the frequency set in E1-09.
If b2-01 = 0 Hz and E1-09 = 0 Hz, the drive will not do Short Circuit Braking.
1 : Coast to Stop
When you enter the Stop command or turn OFF the Run command, the drive turns OFF the output and coasts the
motor to stop.
