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-magnetizing time for the DC Magnetizing start mode.
• Use parameter 2101 to select the start mode.
• After the start command, the drive pre-magnetizes the motor for the
time defined here, and then starts the motor.
• Set the pre-magnetizing time just long enough to allow full motor
magnetization. Too long a time heats the motor excessively.
2104 DC HOLD CTL 0…2
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.
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
).
2108 START INHIBIT 0=OFF, 1=ON
Sets the Start inhibit function on or off. The Start inhibit function ignores
a pending start command in the following situation (a new start
command is required):
• A fault is reset.
0 =
OFF
– Disables the Start inhibit function.
1 =
ON
– Enables the Start inhibit function.
