Page 2: Safety
Safety WARNING! All electrical installation and maintenance work on the drive should be carried out by qualified electricians only. WARNING! The drive and adjoining equipment must be properly grounded. WARNING! Do not attempt any work on a powered drive. After switching off the mains, always allow the intermediate circuit capacitors 5 minutes to discharge before working on the drive, the motor or the motor cable. -

Page 5: Installing The Module
Installing the Module Delivery Check The OTAC-01 module package contains: • OTAC-01 module • Warning stickers in several languages • This manual Mounting WARNING! Follow the safety instructions given in this guide and in the ACS550 User’s Manual. To mount the OTAC-01 module: 1. - Page 6 Wiring – General The pulse encoder should be connected to the OTAC-01 module with cables as specified below. 4 × (2+1) Twisted pair cable with individual Cable construction and overall shields.
- Page 7 Wiring – The Encoder Power The OTAC-01 module does not supply power for the encoder. An external power supply (as diagrammed below) is recommended. The drive’s 24 VDC supply from terminals X1:10 and X1:11 can be used if the total draw on the supply does not exceed 250 mA. Use the following table to determine if the drive’s supply can be used.
- Page 8 Note: Normally, ground the cable shield only at the drive end. However, if the encoder is isolated from the motor, and from ground, then connect the cable shields to both the OTAC module and the encoder housing. Note: Do not route the encoder cables parallel to power (e.g. motor) cables.

Page 13: Start-Up
Start-Up Configuration To configure the operation of the OTAC-01 module: 1. Power up the drive. 2. Use the control panel on the drive and set the parameters described below. Operating Data The following parameters provide feedback from the encoder. The drive sets the parameter values based on measurements or calculations. - Page 14 MOTOR CTRL MODE – Drive uses feedback from an optional encoder. This function requires the Pulse ENABLE Encoder Interface Module (OTAC-01) and an encoder. Operation depends on the setting of parameter 9904 MOTOR CTRL MODE • 9904 = 1 (...
