8.10 Control Mode Selection

The methods and conditions for switching SERVOPACK control modes are described below.

8.10.1 Setting Parameters

The following combinations of control modes can be selected according to the application at hand.

8.10.2 Switching the Control Mode

(1) Switching Internally Set Speed Control (Pn000.1 = 4, 5, or 6)

With the sequence input signals in the factory setting (Pn50A = n.†††0), the control mode will switch when
both /P-CL (/SPD-A) and /N-CL (/SPD-B) signals are OFF (high level).

(2) Switching Other Than Internally Set Speed Control (Pn000.1 = 7, 8, 9, A, or B)

Use the following signals to switch control modes. The control modes switch as shown below for each of the sig-
nal states indicated.
When changing the sequence input signal from the factory setting (Pn50A = n.†††1), allocate the /C-SEL to
an input terminal and change modes with the /C-SEL signal. In this case, input a speed reference (analog voltage
reference) for speed control, and a position reference (pulse train reference) for position control.

Input Signal Selection

The following two types of control mode selection are available for switching from internally set speed control:

• Switching with the /P-CL and /N-CL input signals (pins allocated in factory setting)
• Switching with the /SPD-A and /SPD-B input signals

When using /SPD-A and /SPD-B, they must be allocated with parameter Pn50C. Refer to 7.3.2 Input Circuit Signal Alloca-
tion

The control mode can be switched with either /P-CON or /C-SEL.
When using the /C-SEL signal, the input signal must be allocated. Refer to 7.3.2 Input Circuit Signal Allocation
