2102
STOP FUNCTION
1=COAST, 2=RAMP
Selects the motor stop method.
1 =
COAST
– Selects cutting off the motor power as the stop method.
The motor coasts to stop.
2 =
RAMP
– Selects using a deceleration ramp.
• Deceleration ramp is defined by 2203
DECELER
TIME
1 or 2206
DECELER
TIME
2 (whichever is active).
2103
DC MAGN TIME
0…10 s
Defines the pre-magnetising time for the DC Magnetising start mode.
• Use parameter 2101 to select the start mode.
• After the start command, the drive pre-magnetises the motor for the
time defined here, and then starts the motor.
• Set the pre-magnetising time just long enough to allow full motor
magnetisation. Too long a time heats the motor excessively.
2104
DC HOLD CTL
0=NOT SEL,
2=DC BRAKING
Selects whether DC current is used for braking.
0 =
NOT
SEL
– Disables the DC current operation.
2 =
DC
BRAKING
– Enables the DC injection braking.
• Enables DC injection braking
after modulation has stopped.
• If parameter 2102
STOP
FUNCTION
is 1 (
COAST
), braking
is applied after start is
removed.
• If parameter 2102
STOP
FUNCTION
is 2 (
RAMP
), braking
is applied after ramp.
2105
DC HOLD SPEED
0…360 rpm
Sets the speed for DC Hold. Requires that parameter 2104
DC
HOLD
CTL
= 1 (
DC
HOLD
).
2106
DC CURR REF
0…100%
Defines the DC current control reference as a percentage of parameter
9906
MOTOR
NOM
CURR
.
2107
DC BRAKE TIME
0…250 s
Defines the DC brake time after modulation has stopped, if parameter
2104 is 2 (
DC
BRAKING
).
