Remarks:
Remarks:
This function is not for applications which require a defined (constant) acceleration or deceleration time as the ramps
may vary depending on the load.
A failure may occur if the inertial load of the connected load exceeds 20 times of the inertial load of the motor shaft.
This function is available only in the V/f control mode.
Jogging is not possible under this function.
During the use of an internal or external braking unit the function is not active.
A61 JOG frequency
0.00 - 9.99 Hz
FD: 1.00
Jogging is used for example to adjust a machine in manual operation. As the acceleration and deceleration
ramps are not active in jogging operation a trip (overcurrent) is possible if the jogging frequency is too great.
Remarks:
Remarks:
Jogging operation is started via the control terminals (parameter F9 setting 02 or 03).
Jogging operation is not working if the adjusted frequency is lower than the starting frequency set by A4.
The JOG command should be released appr. 20 ms after releasing a start command. Otherwards it may
happen that the jogging command will not be recognized and the drive will accelerate normal.
A62 Base frequency
30 - A63 Hz
FD: 50
A63 End frequency
30 - 120 (400) Hz
FD: 50
Via the parameter A62 the output frequency at which the output voltage achieves the maximum can be set in
the range of 30 - 120 Hz ( if the maximum frequency was set with an external control unit BE-4 to 400 Hz the
range is 30 - 400 Hz). Normally the nominal frequency of the motor is set here. The relevant information can be
taken from the motor´s type plate.
If in the range above the motor frequency (nominal motor voltage) a frequency range with constant voltage fol-
lows (field weakening range). It is defined by the frequency which is set at A63 (maximum frequency).
Remark:
Remark:
Values >120 Hz are only possible if parameter A64 is set to „400“.
A64 Maximum frequency
120 / 400 Hz
FD: 120
Sets the maximum frequency for parameter A63. This will also influence a lot of other parameters in their
upper limit setting. Factory default setting is 120 Hz.
