Connect on to External Scale
X1 to X7 are used for the secondary circuit. To connect these terminals to the primary
power supply (particularly, the 24 VDC power supply for brake), insulation is required.
Do not connect these terminals to the same power supply.

• Caution
1) The manufacturers applicable external scales for this product are as follows.
• Mitutoyo Corp.
• Magnescale Co., Ltd.
For the details of the external scale product, contact each company.
2) Recommended external scale ratio is 1/40 ≤ External scale ratio ≤ 160
If you set up the external scale ratio to smaller value than 50/position loop gain
(Pr1.00 and Pr.1.05), you may not be able to control per 1 pulse unit. Setup of larger scale ratio may result in larger noise.
Remarks
X1 to X7 are used for the secondary circuit. To connect these terminals to the primary
power supply (particularly, the 24 VDC power supply for brake), insulation is required.
Do not connect these terminals to the same power supply.
