When doing so, set the phase ZZ switch to Z and use a Rotary Encoder with an Open-collector Output. 2: When using phase Z, be sure that the width of phase Z is the same as or wider than the width of phase A. 3. Use one of the following Rotary Encoders: E6A2-CW3C, E6A2-CW5C, E6A2-CWZ3C, E6B2CWZ6C, E6H-CWZ6C, E6C2-CWZ6C, or E6D-CWZ2C. 2 E63-WF Safety Precautions Refer to Warranty and Limitations of Liability. WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Precautions for Correct Use Do not use the Encoder under ambient conditions that exceed the ratings. ● Mounting • Mount to DIN Track as shown in the following diagram. • Hook part (A) at the top of the E63-WF on the DIN Track first and then press in on the E63-WF in the direction indicated by (B). • Removal from DIN Track Pull down on the track stopper (C) with a flat-blade screwdriver and then remove the E63-WF from the DIN Track. When using DIN standard 35 track, keep other devices on the track separated from the E63-WF by at least 30 mm to facilitate mounting and removal. 30 mm min. (B) DIN Track (DIN standard 35) (PFP-100N or PFP-100N2) (A) Track stopper (yellow) (C) 30 mm min. • Do not place the connection cable together with high-voltage cables. Keep it isolated from other cables whenever possible. • The response speed of the E63-WF is 120 kHz. Do not allow the Rotary Encoder to exceed this speed. ● Connection Spurious pulses may be generated when power is turned ON and OFF. Wait at least 0.1 s after turning ON the power to the Encoder before using the connected device, and stop using the connected device at least 0.1 s before turning OFF the power to the Encoder. Also, turn ON the power to the load only after turning ON the power to the Encoder. 3 E63-WF (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
