Drives thrive in washdown applications
The Commander SX range has IP66, Nema 4X ingress protection and is designed for direct to wall or "next to motor" mounting.
Dirt, dust, water and pollution are all environments that mean additional costs whenever a variable speed drive is needed Industries with a requirement for hygienic washdown - food and drink, pharmaceuticals etc - or where there is a high level of dust such as textiles, paper or packaging, all normally require a protective cabinet adding enormously to the total cost of the installation
This is the market for the new Commander SX variable speed AC drive from Control Techniques.
The Commander SX range, from 0.75 to 7.5kW, has IP66 (IEC529), Nema 4X (UL50) ingress protection and is designed for direct to wall or "next to motor" mounting, giving significant savings in cabling, cabinet and installation labour costs.
Commander SX is feature-rich too, with easy setup and commissioning, an internal EMC filter as standard up to 4kW, fieldbus connectivity and LCD text keypad.
"This is a welcome addition to our drives range", says Exec Vice President Sales and Marketing, Phil Sewell.
"This drive has the high precision control and connectivity of the Commander family with the practicality that comes with simple wall-mounting and washdown capability".
Practicality goes even further with Commander SX having a removable gland plate for easy termination and removal of both control and motor cables and is even carefully designed to aid dirt removal during wash-down with slopes greater than 3 degrees from horizontal and radii above 6mm.
Setup and commissioning really is so straightforward that drive installation specialists are not required.
Automatic autotune gives very fast setup and the first 10 parameters on the keypad cover four out of five applications.
Where a more advanced setup is needed, the optional CTSoft windows-based commissioning software makes the process both rapid and painless, with special drive setup wizards for first-time users.
CTSoft also provides storage of parameter sets and gives access to more advanced parameters should they be needed.
The standard backlit LCD text keypad is dual language and has extensive help functions for operator assistance.
Fieldbus connectivity is equally flexible, with Modbus RTU installed as standard and Profibus-DP, DeviceNet, CAN-open, CAN and Interbus all available as options.
The three-phase Commander SX operates in open-loop vector, V/F or optional closed loop vector (with incremental encoder feedback) control modes with an output frequency of 0-400Hz.
The drive accepts speed references inputs 0-10V, 0-20mA or 4-20mA, has five digital inputs (enable, run forward/reverse, jog, local/remote select) and offers linear or S-type acceleration and deceleration ramps.
The drive has a switching frequency of 3-11kHz, with 4kHz set as the default.
A PID controller, DC injection braking and an integral dynamic braking transistor and resistor are all standard.
The braking resistor gives deceleration from nominal speed to stop, of a four-pole motor, typically in less than 3s and larger braking resistors are available to match the duty.
The integral EMC filter complies with the generic emission standard for industrial environments, EN50081-2, for drives up to 4kW.
For larger drives, an optional EMC filter, also rated to IP66, is available. Request a free brochure from Control Techniques ...
