Toshiba VEC008Z - Digital Encoder Manual

Introduction

TOSVERT VF-AS3 series inverter is applicable as PG feedback interface for differential line driver output (TIA/EIA RS422) type encoder.
This manual contains information on installation of this option. See Digital Encoder instruction manual (E6582148) for detail configuration and functions.

Prohibited	Do not use the encoder out of applicable type specified in this manual. This can result in damage or accident.

Interface connector

Connector

15pin D subminiature connector (high density type: DE-15 / HD15) is prepared in this option. Pin numbers of connector are shown the figure in below. Prepare the same type male connector separately for the cable end of interconnection cable.

Wiring

Multi-layer shielded cable is recommended.
When wiring, follow the instructions bellow.

• Use twisted pair wire for A/NA, B/NB and PGVC/PGCC each
• For PGVC, select a pin according to the encoder supply specification. Parameter configuration is also needed (See instruction manual)
• Do not connect any wire to unused pins
• Recommended wire size is 0.25 mm² (AWG26) for signal line (A, NA, B and NB), 0.5mm² (AWG20) for power supply (PGVC and PGCC)
• The cable length is 100m at maximum. At that time, supply voltage drop by wire impedance should be taken into account.

Mounting and removing

Mounting

1. Insert the option into the slot B straightly and slowly. Keep the option from hitting other parts near slot.
   
2. The option should be inserted until the body is totally covered by the slot. (Refer to the picture above)
   

Removing

1. Remove the option in the direction of arrow while pushing the "PUSH" tab by a screw driver.
