Parameter descriptions
Stopping behavior 2
Stop and hold
The drive is brought to a standstill at the set deceleration and remains perma-
nently supplied with cur-rent.
Depending on the setting of the parameter Operation mode 620 the Starting
current
623 is impressed or the Starting voltage 600 is applied as from
Stopping behavior 4
Emergency stop and
Switch off
The drive is brought to a standstill at the emergency stop deceleration. As
soon as the drive is at a standstill, the inverter is disabled after a after a hold-
ing time.
The holding time can be set via the parameter Holding time stop function
638. Depending on the setting of the parameter Operation mode 620, the
Starting current 623 is impressed or the Starting voltage 600 is applied as
Stopping behavior 5
Emergency stop and
hold
The drive is brought to a standstill at the emergency stop deceleration and
remains permanently supplied with current.
Depending on the setting of the parameter Operation mode 620 the Starting
current
623 is impressed or the Starting voltage 600 is applied as from
Stopping behavior 7
DC brake
Direct current braking is activated immediately. In this process, the direct
current set with parameter
Braking current 631 is impressed for the Braking
time
632.
Comply with the notes in chapter 7.3.6 "Direct current brake".
Only available in the configuration 110 (V/f control).
Comply with chapter 7.6.5.5 "Release brake" on addressing mechanical brakes.
When a synchronous motor is connected, BONFIGLIOLI recommends setting
Operation mode 630 =
22.
637 Switch-Off Threshold Stop Function
The
Switch-Off Threshold Stop Function 637 defines the frequency as from which a stand-still of the
drive is recognized. This percentage parameter value is relative to the set
Maximum frequency 419.
The switch-off threshold is to be adjusted according to the load behavior of the drive and the device
output, as the drive must be controlled to a speed below the switch-off threshold.
Switch-Off Threshold Stop Function
WARNING
If the motor builds up a stopping torque, it may be possible that the switch-off thresh-
old stop function is not reached due to the slip frequency and the standstill of the drive
is not recognized. In this case, increase the value of the Switch-off threshold stop func-
tion
637.
638 Holding time stop function
The
Holding time stop function 638 is considered in stopping behaviors 1 and 4. Controlling to speed
zero leads to a heating of the motor and should only be done for a short period in internally ventilated
motors.
