5.7.1 Switching Internal Set Speed Control (Pn000.1 = 4, 5, or 6)
Conditions for switching in internal set speed control are as shown below.
(1) Factory-set Input Signal Allocations (Pn50A.0 = 0)
The control mode can be switched using /P-CL and /N-CL signals.
• When Pn000.1 = 5 (Internal set speed control ⇔ Position control), the soft start function will operate only
when selecting the internal set speed. The soft start function cannot be used with pulse reference input.
• When switching to pulse reference input during operation at either of the three speeds (1st speed to 3rd
speed), the pulse reference will not be received by the SERVOPACK until after the positioning completed
(/COIN) signal is output. Always begin the output of the pulse reference from the host controller after the
positioning completed (/COIN) signal is output from the SERVOPACK.
<Operation Example using Control Modes of Internal Set Speed Control + Soft Start <=> Position Control
(Pulse Train Reference)>
Note 1. The t1 value is not affected by whether the soft start function is used.
A maximum delay of 2 ms occurs in loading /P-CL and /N-CL.
2. The speed is decelerated for the time set in Pn306, and the speed control will be changed to the position control
after the motor comes to a stop.
3. The position control can be changed to the speed control while the motor is rotating.
Use /P-CON signal to switch forward/reverse rotation when internal set speed control is used.
(Forward: /P-CON = OFF, reverse: /P-CON = ON)
