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).
