A-B 1756-M08SEG Module Rockwell Servo Control

Analog Motion Modules

The ControlLogix family of analog servo modules is a cost effective option for

closed-loop or open-loop motion control of devices that support an analog

motion interface. The analog servo modules provide a ±10V analog

output-command reference and support a variety of position feedback devices.

As many as two axes can be controlled per module, and multiple modules can

be used to provide as many as 32 axes of control per ControlLogix controller.

General

The power converter modules DCS800-S have the protection class IP00 and are to be mounted in a cubicle or finger protected area. 

There are different sizes (D1. D2. D3. D4. D5. D6. D7), graduated in terms of current and voltage ranges.

All units are equipped with the DCS800 Control Panel. 

It can be snapped into place on the power converter module or installed in the switchgear cubicle door by means of amounting kit. 

Accessories such as external fuses, line reactors etc. are also available, to complete the drive system. 

All converter modules up to 525 V and 1000 A (D1...D4) are equipped with field exciters.

The power section of the converters is available as single  (2-Q) bridge or double (4-Q) bridge. 4-Q drives are required for regenerative breaking. 

4-Q drives can be built by:

–Double (4-Q) armature bridge or –Single (2-Q) armature bridge plus a double (4-Q) field converter bridge

The bridge type has an influence on the maximum output voltage of the converter. See table below.

SERCOS Interface Modules

The SERCOS interface modules use a single, digital fiber-optic link, which

eliminates as many as 18 digital wires per axis. Detailed drive-status

information can be sent from drive to controller and from controller to drive.

The SERCOS interface modules can connect to these servo drives:

• 2093 Kinetix 2000 multi-axis servo drive

• 2094 Kinetix 6000 multi-axis servo drive

• 2099 Kinetix 7000 high-power servo drive

• 2098 Ultra3000 SERCOS servo drive

The PlantPAx® 5.0 distributed control system (DCS) introduces new process functionality native to controllers,

cyber-secured architectures, and improved system availability and workflows. 

These benefits help reduce the complexity of traditional DCS and overall costs at all phases of the plant lifecycle for hybrid and Process industries. 

Accelerate your digital transformation with our latest PlantPAx® 5.0 DCS version and unlock 

more opportunities with our ControlLogix® 5580 and CompactLogix™ 5380 Process controllers.

Restrictions

• Volts per Hertz operation requires the use of the Custom User Defined Controller Communication Format.

If another Controller Communication Format is selected (e.g. Velocity Control, 

Position Control or User Defined Control) and the drive is configured for Volts per Hertz operation, 

the Drive Module will not connect to the controller.

• This module sometimes experiences PMI Comm faults during power cycles.

For example, when the Drive Module and PMI processor are power-cycled the drive module initializes its interface

with the PMI processor. During the transition from initialization to synchronized communication,

the Drive Module sometimes experiences communication faults and warnings. 

ATTENTION: 

The installation of the drive must be planned such that all cutting, drilling, tapping and welding can be accomplished with the drive removed from the enclosure. 

The drive is of the open type construction and any metal debris must be kept from falling into the drive. 

Metal debris or other foreign matter may become lodged in the drive circuitry resulting in component damage. ! 

An incorrectly applied or installed drive can result in component damage or a reduction in product life. 

Wiring or application errors, such as, undersizing the motor, incorrect or inadequate AC supply, 

or excessive ambient temperatures may result in malfunction of the system. ! 

Only qualified personnel familiar with DC drives and associated machinery should plan or implement the installation, 

start-up and subsequent maintenance of the system.

Failure to comply may result in personal injury and/or equipment damage.

These faults and warnings can be cleared with a clear faults command. 

You may have to perform a reset after power-up, or perform multiple resets.
