Parameters
2104 DC CURR CTL 0…2 1 0 (
NOT SEL
)

Selects whether DC current is used for braking or DC Hold.
0 =
NOT SEL
– Disables the DC current operation.
1 =
DC HOLD
– Enables the DC Hold function. See the diagram.
• Requires parameter 9904
MOTOR CTRL MODE
= 1 (
VECTOR
:
SPEED
)
• Stops generating sinusoidal current and injects DC into the motor when
both the reference and the motor speed drop below the value of
parameter 2105.
• When the reference rises above the level of parameter 2105 the drive
resumes normal operation.
2 =
DC BRAKING
– Enables the 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 1 rpm 5 rpm
Sets the speed for DC Hold. Requires that parameter 2104
DC HOLD CTL
= 1 (
DC HOLD
).
2106 DC CURR REF 0…100% 1% 30%
Defines the DC current control reference as a percentage of parameter 9906
MOTOR NOM CURR
.
2107 DC BRAKE TIME 0.0…250.0 s 0.1 s 0.0 s
Defines the DC brake time after modulation has stopped, if parameter 2104 is 2 (
DC BRAKING
).
2108 START INHIBIT 0, 1 1 0 (
OFF
)
Sets the Start inhibit function on or off. If the drive is not actively started and running, the Start inhibit function ignores
a pending start command in any of the following situations and a new start command is required:
• A fault is reset.
• Run Enable (parameter 1601) activates while start command is active.
• Mode changes from local to remote.
• Control switches from
EXT
1 to
EXT
2.
• Control switches from
EXT
2 to
EXT
1.
0 =
OFF
– Disables the Start inhibit function.
1 =
ON
– Enables the Start inhibit function.
2109 EMERG STOP SEL -6…6 1 0 (
NOT SEL
)
Defines control of the Emergency stop command. When activated:
• Emergency stop decelerates the motor using the emergency stop ramp (parameter 2208
EMERG DEC TIME
).
• Requires an external stop command and removal of the emergency stop command before drive can restart.
0 =
NOT SEL
– Disables the Emergency stop function through digital inputs.
1 =
DI
1 – Defines digital input
DI
1 as the control for Emergency stop command.
• Activating the digital input issues an Emergency stop command.
• De-activating the digital input removes the Emergency stop command.
2…6 =
DI
2…
DI
6 – Defines digital input
DI
2…
DI
6 as the control for Emergency stop command.
• See
DI
1 above.
-1 =
DI
1(
INV
) – Defines an inverted digital input
DI
1 as the control for Emergency stop command.
• De-activating the digital input issues an Emergency stop command.
• Activating the digital input removes the Emergency stop command.
-2…-6 =
DI
2(
INV
)…
DI
6(
INV
) – Defines an inverted digital input
DI
2…
DI
6 as the control for Emergency stop command.
• See
DI
1(
INV
) above.
2110 TORQ BOOST CURR 15…300% 1% 100%
Sets the maximum supplied current during torque boost.
• See parameter 2101
