170 Parameters
21.02
Magnetization time
Defines the pre-magnetization time when
• parameter
21.01 Vector start mode
is set to
Const time
(in vector motor control mode), or
• parameter
21.19
Scalar start mode
is set to
Const time
(in scalar motor control mode).
After the start command, the drive automatically
premagnetizes the motor for the set time. To ensure full
magnetizing, set this parameter to the same value as, or
higher than, the rotor time constant. If not known, use the
rule-of-thumb value given in the table below:
Note:
This parameter cannot be changed while the drive
is running.
500 ms
0…10000 ms
Constant DC magnetizing time.
1 = 1 ms
21.03
Stop mode
Selects the way the motor is stopped when a stop
command is received.
Additional braking is possible by selecting flux braking
(see parameter
97.05
Flux braking
).
Ramp
Coast
Stop by switching off the output semiconductors of the
drive. The motor coasts to a stop.
WARNING!
If a mechanical brake is used, make
sure it is safe to stop the drive by coasting.
0
Ramp
Stop along the active deceleration ramp. See parameter
group
23 Speed reference ramp
or
28 Frequency
reference chain
.
1
Torque limit
Stop according to torque limits (parameters
30.19
and
30.20
). This mode is only possible in vector motor control
mode.
2
21.04
Emergency stop mode
Selects the way the motor is stopped when an emergency
stop command is received.
The source of the emergency stop signal is selected by
parameter
21.05 Emergency stop source
.
Ramp stop
(Off1)
Ramp stop (Off1)
With the drive running:
• 1 = Normal operation.
• 0 = Normal stop along the standard deceleration ramp
defined for the particular reference type (see section
Reference ramping
on page
67
). After the drive has
stopped, it can be restarted by removing the
emergency stop signal and switching the start signal
from 0 to 1.
With the drive stopped:
• 1 = Starting allowed.
• 0 = Starting not allowed.
0
No.
