Parameters
2104 DC HOLD 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 EXT1 to EXT2.
• Control switches from
EXT2 to EXT1.
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 =
DI1 – Defines digital input DI1 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 =
DI2…DI6 – Defines digital input DI2…DI6 as the control for Emergency stop command.
•See
DI1 above.
-1 =
DI1(INV) – Defines an inverted digital input DI1 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 =
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for Emergency stop command.
•See
DI1(INV) above.
2110 TORQ BOOST CURR 15…300% 1% 100%
Sets the maximum supplied current during torque boost.
• See parameter 2101
START FUNCTION.
2113 START DELAY 0.0…60.00 s 0.01 s 0.00 s
Defines the Start delay. After the conditions for start have been fulfilled, the drive waits until the delay has elapsed
and then starts the motor. Start delay can be used with all start modes.
•If
START DELAY = zero, the delay is disabled.
• During the Start delay, alarm 2028
START DELAY is shown.
