Brake release time
-10.00 to -0.01 s
The "Release brake" command is delayed in relation to enabling of the
gating pulses for thyristors and controllers (i.e. operating state I, II or --) by
the delay time set in this parameter. During this period, the motor rotates
against the closed brake. This setting is useful, for example, for vertical
loads.
0.00 to +10.00 s
When a "Switch-on" or "Inching" or "Crawling" command is input with
"Operating enable", the drive dwells in operating state o1.0 for the delay
period set in this parameter; the internal controller enabling signal, and thus
enabling of the thyristor gating pulses, do not take effect until the delay
period has elapsed so as to give the holding brake time to open.

Brake closing time
When the "Switch-on" or "Inching" or "Crawling" command is cancelled, or
when the "Switch-on" command is not applied, or when the "Fast stop"
command is input, the internal controller disabling signal, and thus the
thyristor gating pulse disabling signal, is not actually activated after n<nmin
has been reached until the time delay set in this parameter has elapsed.
During this period, the drive continues to produce a torque (operating state
I, II or – –), so as to give the holding brake enough time to close.

P089 Maximum wait time for voltage to appear at power section
When the line contactor has dropped out and the "Switch-on" or "Inching"
or "Crawling" command is applied, the converter dwells in operating state
o4 until voltage appears at the power section. The corresponding fault
message is activated if no power section voltage is detected within the
period specified by this parameter (response threshold for function which
checks for voltage at power section, see parameter P353).

P090 Stabilization time for line voltage
When the "Switch-on" or "Inching" or "Crawling" command is applied, or
after a phase failure has been detected in the mains supply with active
"Automatic restart" function (P086>0), the converter dwells in operating
state o4 until voltage appears at the power section. Line voltage is not
assumed to be applied to the power terminals until the amplitude, frequency
and phase symmetry have remained within the permissible tolerance for a
period exceeding the setting in this parameter.
Caution:
The setting in P090 must be lower than the settings in P086 (except when
P086=0.0) and P089!

P091 Setpoint threshold
i001: Threshold for function "Switch on only if setpoint is low“
The converter can be switched on only if a setpoint
|K0193|
≤
P091.001 is applied to the ramp-function generator
input. If the applied setpoint is higher, the converter dwells in
state o6 after "switch-on" until the absolute setpoint value is
≤
P091.001.
i002: Threshold for function
"Automatic pulse disable if setpoint is low“ [SW 2.0 and later]
If |n-set| (|K0193|) and |n-act| (K0166) are less than P091.002,
the firing pulses are disabled and the drive goes into state o2.0.
