Code Name/Description Setting range Factory settings
Level of standstill DC injection current.
Note:
The parameter is accessible if [Motor control type] (Ctt) does not equal [FVC] (FUC) and if [Type of movement] (bSt) is the same
as [Translation] (HOr) .
Caution!
Check that the motor will withstand this current without overheating.
Failure to follow this instruction can result in equipment damage.
bEd
[Engage at reversal] [No]
(nO)
nO [No] (nO) : The brake does not engage.
YES [Yes] (YES) : The brake does engage.
This parameter can be used to select whether or not the brake engages on transition to zero speed when the operating direction is reversed.
JdC [Jump at reversal]
1)
0 to 10 Hz [Auto] (AUtO)
The parameter is accessible if [Motor control type] (Ctt) does not equal [FVC] (FUC) and if [Bewegungsart] (bSt) is the same as [Hoist] (UEr) .
AUtO [Auto] (AUtO) : The inverter takes a value equal to the rated slip of the motor, calculated using the inverter parameters.
-
0 to 10 Hz
: Manual adjustment
When the reference direction is reversed, this parameter can be used to avoid loss of torque (and consequential release of load) on transition to
zero speed. The parameter is irrelevant if [Brake rot. rev.] (bEd) = [Yes] (YES) .
ttr [Time to restart]
1)
0 to 15 s 0
Time between the end of a brake engage sequence and the start of a brake release sequence
1) This parameter can also be accessed via the [SETTINGS] (SEt-) menu.
2) In is the same as the rated current specified in the installation instructions and on the nameplate of the inverter.
Parameter that can be modified during operation or when stopped.
