Jog frequency
(Jog frequency)

-400.0 ... 400.0 Hz
{ 0.0 }
When using the SimpleBox or ParameterBox to control the FI, the jog frequency is the initial
value following enabling.
Alternatively, when control is via the control terminals, the jog frequency can be activated via one
of the digital inputs.
The setting of the jog frequency can be carried out directly via this parameter or, if the FI is
enabled via the keyboard, by pressing the OK key. In this case, the actual output frequency is set
in parameter P113 and is then available for the next start.
NOTE: Specified setpoints via the control terminals, e.g. jog frequency, fixed frequencies or
analog setpoints, are generally added with the correct sign. The set maximum
frequency (P105) cannot be exceeded and the minimum frequency (P104) cannot be
undershot.
P114
Brake delay off
(Brake release time)
S P
0 ... 2.50 s
{ 0.00 }
Electromagnetic brakes have a delayed reaction time during release, which depends on physical
factors. This can lead to the motor starting while the brake is still applied, which will cause the
inverter to switch off with an overcurrent report.
This release time can be taken into account in parameter P114 (Braking control).
During the adjustable release time, the FI supplies the set absolute minimum frequency (P505)
thus preventing movement against the brake.
See also the parameter >Brake reaction time< P107 (setting example).
NOTE: If the brake release time is set to "0", then P107 is the brake release and reaction
time.

Option monitoring

Monitoring of communication at system bus level (in case of error: error message 10.9)
Array levels: Setting values, for each array:
[-01] = Extension 1 (BUS TB)
[-02] = Extension 2 (second I/O TB)
[-03] = Extension 3 (first I/O TB)
[-04] = Extension 4 (reserved)
0 = Monitoring off
1 = Auto: communications are only monitored if
an existing communication is interrupted. If
after switching on the mains a module which
was previously present is not detected, this
does not result in an error.
The monitoring only becomes active when
one of the extensions commences
communication with the FI.
2 = Monitoring active immediately, the FI starts
monitoring the corresponding module
immediately after it is switched on. If the
module is not detected after the mains have
been switched on, the FI remains in the
state “Not on standby” for 5 seconds and
then triggers an error message.
Note: If error messages which are detected by the optional module (e.g. errors at field bus
level) are not to result in a shut-down of the frequency inverter, parameter (P513) must
also be set to the value {-0,1}.
