(3) The TJ Mode
The relationships between the acceleration pulse, deceleration pulse, and brake interval are as shown in the table
below.
*
The 256 TRACK CHECK does not produce an actuator drive signal as shown in the table above, rather because the mode is such that the TES signal is
counted when the tracking loop is off, it is necessary to provide a feed to the feed motor.
*
When the track jump sequence (a, b, c) is completed, the servo command register is reset automatically.
*
When a new command has been input when the track jump is in process, that command is executed at that instant.
*
In the 1 TRACK JUMP #3 command there is no brake period (period c), but rather caution is warranted because it is necessary to generate the brake
mode using an external circuit.
*
Although in the 2TRACK JUMP IN (OUT) of the new track jump mode the brake period (period c) did not exist for the LC78620E/21E/25E ICs, in this IC
period C has been changed to 60 ms.
