If both JOG keys are simultaneously pressed, then the instantaneous frequency is
kept (constant velocity phase) and alarm A0923 is output. When a key is pressed,
the drive inverter accelerates the motor to the fixed frequency in the time entered in
P1060. This frequency is only exited after the key has been cancelled and the drive
then brakes down to 0 Hz in the time entered in P1061.
In addition to the explicit parameterization (P1055 and P1056), the JOG
functionality is also enabled via parameter P0700 or P0719 (implicit
parameterization). In this case, if a value is assigned to P0700, the BICO
parameter is appropriately modified.
Example: Command source via "USS on BOP link" interface
a) Standard method → P0700 = 4
b) BICO method → P1055 = 2032.8
P1056 = 2032.9
