The limit value 20% of torque current cannot be undershot by a smaller analog setpoint (P400/405 = 2)
(with P300 = 1, not below 10%)!
401% = OFF
is for switching the torque current limit off! This is also the basic setting for the FI.
P113 (P)
Jog frequency
always visible
-400.0 ... 400.0 Hz
[ 0.0 ]
When using the
ControlBox
or
ParameterBox
to control the FI, the jog frequency is the starting value
following successful enable.
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 done directly via this parameter or, if the FI is enabled via the
keyboard, by pressing the ENTER 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 (P)
Brake delay off
always visible
0 ... 2.50 s
[ 0.00 ]
Electromagnetic brakes have a delayed reaction time during ventilation, which depends on physical
factors. This can lead to the motor running while the brake is still applied, which will cause the inverter
to switch off with an overcurrent report.
This ventilation time can be taken into account in parameter P114 (Braking control).
During the adjustable ventilation 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 ventilation time is set to "0", then P107 is the brake ventilation and reaction
time.
