AP-62 Broken Belt Delay
Range: Function:
10 s* [0 - 600 s] Sets the time for which the Broken Belt conditions must be active before carrying out the action selected
in par. AP-60 Broken Belt Function.
AP-75 Short Cycle Protection
Option: Function:
[0] * Disabled Timer set in par. AP-76 Interval between Starts is disabled.
[1] Enabled Timer set in par. AP-76 Interval between Starts is enabled.
AP-76 Interval between Starts
Range: Function:
0 s*
[0 to 3600 s] Sets the time desired as minimum time between two starts. Any normal start command (Start/Jog/Freeze)
will be disregarded until the timer has expired.
AP-77 Minimum Run Time
Range: Function:
0 s* [0 - par. AP-76 ] Sets the time desired as minimum run time after a normal start command (Start/Jog/Freeze). Any normal
stop command will be disregarded until the set time has expired. The timer will start counting following
a normal start command (Start/Jog/Freeze).
The timer will be overridden by a Coast (Inverse) or an External Interlock command.
NB!
Does not work in cascade mode.
B-00 DC Hold Current
Range: Function:
50 %* [0 - 160. %] Enter a value for holding current as a percentage of the rated motor current I
M,N
set in par. P-03 Motor
Current. 100% DC holding current corresponds to I
M,N
.
This parameter holds the motor (holding torque) or pre-heats the motor.
This parameter is active if [1] DC hold/Preheat is selected in par. H-80 Function at Stop.
NB!
The maximum value depends on the rated motor current.
NB!
Avoid 100 % current for too long. It may damage the motor.
B-10 Brake Function
Option: Function:
[0] * Off No brake resistor installed.
Brake resistor incorporated in the system, for dissipation of surplus brake energy as heat. Connecting a
brake resistor allows a higher DC link voltage during braking (generating operation). The Resistor brake
function is only active in frequency converters with an integral dynamic brake.
B-17 Over-voltage Control
Option: Function:
Over-voltage control (OVC) reduces the risk of the frequency converter tripping due to an over voltage on
the DC link caused by generative power from the load.
[0] Disabled No OVC required.
[2] * Enabled Activates OVC.
