EZ LIMO PWA II Series Motorized Cylinders

The utilizes our unique closed loop control to maintain positioning operation even during abrupt load fluctuations and accelerations. The rotor position detection sensor constantly monitors the rotation. When an overload condition is detected, it will instantaneously regain control using the closed loop mode.

Offering all of the benefits of a stepping motor:

• High Response
• No Tuning
• No Hunting

Compact Size and High Thrust Force

The PWA II Series cylinders provide high thrust force. The maximum thrust force of the PWA6 and PWA8 are 1000 N (600 N in push-motion operation) and 5000 N (3500 N in push-motion operation), respectively.

Short Cycle Operation

The time required for an operating cycle can be reduced by linking the pressure speed and the approach speed (when the rod approaches the load).

Construction

The built-in guide mechanism in the cylinder eliminates the need to provide an external guide mechanism before using the cylinder.

 

The built-in home/limit sensors in the cylinder save the customer the trouble of having to install sensors.

Push-Motion Operation

In this operation, the cylinder can keep the rod push against a load, etc.

 

Pressurized Positioning Operation

In this operation, the cylinder can perform high-accuracy positioning while applying pressure to the rod.

Powerful Controller

Controller

The controller combines all of the functions needed to operate a linear slide in an easy to use solution. All EZ Limo controllers feature a vibration suppression function to reduce common areas where vibration can occur. The controllers are available in two power supply voltages: single-phase 100-115 VAC and single-phase 200-230 VAC.

The controller can be used as an absolute unit by connecting an optional battery.

Choose Controller or Driver Mode
The EZ Limo can be combined with your existing controller to serve as a driver controlling the linear slide by pulse input.

Teaching Function
You can directly move the table to a desired position and store the position obtained, or use a teaching pendant to move the table to a desired position and then store it. Up to 63 points of positioning data can be set.

Linked Operation
By linking multiple sets of operation data, simply input a start signal. You can then change the linear slide speed without physically stopping the linear slide.

 

Push-Motion Function

The rod can be held in a state of being pushed against the load or similar object, as with an air cylinder. the force used to push the load (push force) can be changed.

 

Area Output Signal

A signal is output when the linear slide table or cylinder rod enters a set area arbitrarily set along the stroke. One set area can be set.

 

Up to 63 Points of Positioning Data

Up to 63 points of positioning data can be set in simple steps. The positioning operation can be performed in one of two ways: using the selective positioning method, where desired data is selected and executed by the signals from the host controller; or the sequential positioning method, in which all data is executed sequentially when a start signal is input.

Output of Current Position and Error Code

The current position, error code and other data can be output to an external device.

 

Operation / Data Setting

You can easily perform all tasks from operation to data setting by using our teaching pendant or data editing software.

	Data Editing Software (Sold separately) EZED2

Two Modes to Set Positioning Data Setting

Data can be set in the absolute mode (absolute-position specification) or the incremental mode (incremental-position specification).

Absolute Mode: The absolute position (distance) from the reference point is set.

Incremental Mode: The position achieved by the motor after the last movement (=current position) is defined as the starting point for the next movement.

Acceleration / Deceleration Adjustment

Four patterns of acceleration/deceleration setting are possible according to your operating conditions. Acceleration and deceleration can be set separately.

Speed Filter

Use this filter to suppress disturbances during starting and stopping or to reduce vibration during low-speed operation. With the speed filter function you can control the motor to minimize speed fluctuations even when switching the speed rapidly between operation commands.

The set value can be adjusted digitally (over a range of 1 to 100). Increasing the set value makes the movement smoother while decreasing the synchronism with the command.
