Microstepping drives with a choice of communication protocolsNew from Applied Motion Products Inc (AMP) and available with full support from Mclennan, STF series open-loop microstepping drives are designed for optimal use where machine builders and OEMs prefer to integrate industrial Ethernet or other industry-standard fieldbus protocols into automation control systems. These intelligent drives offer a choice of interfaces including EtherCAT, EtherNet/IP, CANopen, Modbus, Ethernet (UDP and TCP) and RS-485.

Various operational modes, dependent on the communication interface, include the ability to stream motion commands from the host controller or store complete programs that can be host-controlled for multiple-axis synchronisation. Furthermore, a compliment of eight digital inputs and four digital outputs provide local control of machine functions. All STF drives include dual-port communications to enable daisy-chain connections for multiple drives, HMIs or other connected devices back to the host controller.

STF series microstepping drives are available in three power versions covering up to 3.0, 6.0 and 10.0A/phase. AMP's well-proven drive architecture includes advanced current control with anti-resonance and torque ripple smoothing that ensures maximum performance and optimal power over a wide speed range. The drives suit compatible NEMA microstepping motors (two-phase, bipolar) from size 8 to size 34 – also available from Mclennan. The panel-mounted STF series includes protection for short circuit, over- and under-voltage, and over-temperature. For installation convenience, all are DC powered (12-48V DC for the 3A and 6A versions, and 24-70V DC for the 10A version).

STF series stepper drives are designed for accurate, open-loop control of step motors. For applications where an encoder may be required for position verification, Mclennan offers AMP's ST series stepper drives. Where full closed-loop control of a microstepping motor is necessary, AMP's competitively priced stepSERVO products offer proven performance with increased torque, higher acceleration and, ultimately, better throughput than traditional step motor systems. Both ST and StepSERVO drive series are offered with a full range of fieldbus and communications interfaces.

Mclennan supplies and fully supports the comprehensive range of AMP stepper and servo-based motion control products. Complete specifications are available on request from Mclennan at www.mclennan.co.uk.
