YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual
All Modes
Sets the frequency to start executing DC Injection Braking, Short-Circuit Braking, and Zero
Servo. Enabled when the stopping method is set for ramp to stop (b1-03 = 0).
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the DC Injection Braking current as a percentage of the drive rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time of DC Injection Braking (Zero Speed Control when in CLV and CLV/PM) time at
start. Disabled when set to 0.00 seconds.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time of DC Injection Braking (Zero Speed Control when in CLV and CLV/PM) at stop.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the magnetic flux compensation as a percentage of the no-load current value (E2-03).
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the DC Injection Braking 2 current as a percentage of the drive rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time for Short Circuit Braking operation at start.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the Short Circuit Braking operation time at stop.
V/f V/f w/PG
OLV/PM AOLV/PM
Determines the current level for Short Circuit Braking. Set as a percentage of the motor rated
current.
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled
1: Enabled
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the current level at which the speed is assumed to be detected and Speed Search is ended.
Set as a percentage of the drive rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets output frequency reduction time during Speed Search.
V/f V/f w/PG
OLV/PM AOLV/PM
Determines how much to lower the V/f ratio during Speed Search.
V/f during Speed Search equals the V/f setting multiplied by b3-04.
All Modes
When using an external contactor on the output side, b3-05 delays executing Speed Search after
a momentary power loss to allow time for the contactor to close.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the current injected to the motor at the beginning of Speed Estimation Speed Search. Set as
a coefficient for the motor rated current.
