11.4.3 Setting the required parameters for manual pulse generator operation

The "Parameters" must be set to carry out manual pulse generator operation.

The following table shows the setting items of the required parameters for carrying out manual pulse generator operation. When only manual pulse generator operation will be carried out, no parameters other than those shown below need to be set. (Use the initial values or setting values within a range where no error occurs for trouble-free operation.)

Parameters

	Setting item	Setting requirement	Factory-set initial value
			(setting details)
Pr.1	Unit setting		3 (pulse)
Pr.2	No. of pulses per rotation (Ap) (Unit: pulse)		20000
Pr.3	Movement amount per rotation (Al) (Unit: pulse)		20000
Pr.4	Unit magnification (Am)		1 (1-fold)
Pr.5	Pulse output mode		1 (CW/CCW mode)
			0 (current value increases by
Pr.6	Rotation direction setting		forward run pulse output)
Pr.11	Backlash compensation amount (Unit: pulse)		0
Pr.12	Software stroke limit upper limit value (Unit: pulse)		2147483647
Pr.13	Software stroke limit lower limit value (Unit: pulse)		–2147483648
Pr.14	Software stroke limit selection		0 (current feed value)
Pr.15	Software stroke limit valid/invalid setting		0 (valid)
Pr.17	Torque limit setting value (Unit: %)		300
			0 (Manual pulse generator
Pr.22	Input signal logic selection
			input is negative logic.)
			0 (Pulse output to drive unit is
Pr.23	Output signal logic selection
			negative logic.)
			0 (4 times multiplication of A
Pr.24	Manual pulse generator input selection
			phase/B phase)

:Setting always required.

:Set according to requirements (Leave set to the initial value when not used.)

REMARK

•Parameter settings work in common for all control using the QD75. When carrying out other control ("major positioning control", "high-level positioning control", "OPR positioning control"), the respective setting items must also be matched and set.

• Parameters are set for each axis. But Pr.22 Manual pulse generator input logic

(b8),

Pr.24

is set only for axis 1. (The setting for axes 2,3, and 4 is ignored.)

•Refer to Chapter 5 "Data Used for Positioning Control" for setting details.
