LS-56P/57P/58P servo amplifiers are designed for applications using Panasonic A or S series motors, brushless, or brush-commutated DC motors up to 1 HP. They provide a full set of features for motor control including amplifier enable, direction enable inputs for connection to limit switches, and all necessary protections for the motor and amplifier. LS-56P/57P/58P can be used in conjunction with digital servo controllers or as stand-alone drives. Input gain, loop gain and offset can be adjusted. The offset potentiometer can also be used as on-board full range reference signal. A configurable component carrier and mode switches are used to select the operation mode and to customize the amplifiers for specific motor parameters. Individually adjustable peak and continuous current limits allow high acceleration without sacrificing protection against continuous overloads. Peak current time can be adjusted from 50 ms to 3 sec.

LS-5Y PWM servo amplifier is designed for applications using DC brush type motors up to 1/2 HP. It provides a full set of features for motor control including amplifier enable, direction enable inputs for connection to limit switches, and all necessary protections for the motor and amplifier. LS-5Y can be used in conjunction with digital servo controllers or as a stand-alone drive. Loop gain, input gain and offset can be adjusted with multi-turn potentiometers. The offset potentiometer can also be used as on-board full range reference signal. A configurable component carrier holds 5 resistors and 2 capacitors for setting of various gain and current parameters to customize the amplifiers for different loads. Individual peak and continuous current limits allow high acceleration without sacrificing protection against continuous overloads. Peak current time can be adjusted from 3 to 0 sec. LS-5Y is available in 4 different models to address application requirements for specific power supply voltage range and direction enable inputs functionality.
