Yes The shaft will begin rotating after receiving a Start command,
with delay. During this delay, the drive is building up the mag-
netic field in the motor. This allows the drive to start in vector
mode with less starting current.
This parameter filters the slip frequency applied to the motor, which can help improve
the dynamic response of the drive. This parameter produces the following results based
on the parameter value:
If the parameter is configured to 100 ms, the drive will produce stable conditions to a
change in load, in most cases.
If the parameter is configured to less than 100 ms, the drive will be able to react quickly
to a change in load, but may over-compensate its reaction to the load.
If the parameter is configured to greater than 100 ms, the drive will react very slowly to
a change in load and will need a longer time to compensate for the difference between
the setpoint and the actual frequency.
This parameter shows the Flux producing current (as a percentage of motor rated cur-
rent) that is being applied to the drive.
This parameter shows the Torque producing current (as a percentage of motor rated cur-
rent) that is being applied to the drive.
This parameter can be used to define how the drive responds to an undervoltage opera-
tion when parameter 501 is set for Vector or Linear Auto mode. The following data values
may be assigned to this parameter:
Parameter Value Description
CTS No Msg The drive will coast to a stop when an undervoltage condition
(power-down) is detected.
Coast Stop The drive will coast to a stop when an undervoltage condition
(power-down) is detected. In this mode, however, the drive
will generate an undervoltage fault, which will be registered
in the fault log.
Ramp Down With this setting, if power is lost, the drive ramps the motor
down at a decel rate of Decel 1. When the drive is fully ramped
down, the drive will generate an undervoltage fault. If power
is restored, the drive will continue to ramp to a stop and will
fault.
Quick Ramp Same as Ramp Down, except the shorter ramp time (Decel 1
or Decel 2) will be used.
Controlled With this setting, if power is lost, the drive decelerates the
motor, trying to regulate the bus voltage to the undervoltage
level. If power is restored, the drive accelerates to the com-
mand frequency without faulting. If the drive reaches the
stopped condition, it will generate an undervoltage fault.
ContrNoMsg Same as Controlled, but without generating an undervoltage
fault.
