Ac Brake Max. Current - Danfoss VLT FC 100 Series Programming Manual

Parameter Description
2-15 Brake Check
Option:
3 3
[0] Off
*
[1] Warning
[2] Trip
[3] Stop and
trip
[4] AC brake
NOTE!
Remove a warning arising in connection with Off [0] or
Warning [1] by cycling the line power supply. The fault
must be corrected first. For Off [0] or Warning [1], the
Adjustable frequency drive keeps running even if a fault is
located.

3.4.3 2-16 AC brake Max. Current

2-16 AC brake Max. Current
Range:
100.0 %
*
NOTE!
2-16 AC brake Max. Current will not have effect when
1-10 Motor Construction = [1] PM, non-salient SPM.
2-17 Over-voltage Control
Option:
[0] Disabled
[2] Enabled
*
NOTE!
2-17 Over-voltage Control will not have effect when
1-10 Motor Construction = [1] PM, non-salient SPM.
3-30
VLT
Function:
ripple amplitude before braking + 1%.
Brake check OK.
Monitors brake resistor and brake IGBT for a
short-circuit during operation. If a short-circuit
occurs, a warning appears.
Monitors brake resistor and brake IGBT for a
short-circuit, and to run a test for brake resistor
disconnection during power-up.
Monitors for a short-circuit or disconnection of
the brake resistor, or a short-circuit of the brake
IGBT. If a fault occurs, the Adjustable frequency
drive cuts out while displaying an alarm (trip
locked).
Monitors for a short-circuit or disconnection of
the brake resistor, or a short-circuit of the brake
IGBT. If a fault occurs, the Adjustable frequency
drive ramps down to coast and then trips. A trip
lock alarm is displayed.
Function:
[ 0.0 - 1000.0 %]
Function:
No OVC required.
Activates OVC.
