Description
The National Instruments ISM-7401 is an integrated stepper designed for precision and compatibility, operating in conjunction with the NI-7330, NI-7340, and NI-7350 motion controllers. It supports an operating voltage range of 12 VDC to 60 VDC and can achieve an operating frequency of 16 kHz through Pulse Width Modulation (PWM), which aids in precise motor control and reduced operational noise.
This stepper motor accepts digital input voltages ranging from a minimum of 4 VDC to a maximum of 30 VDC, catering to various control systems. It incorporates robust protection features to safeguard against over-voltage, under-voltage, over-current, and over-temperature conditions. An under-voltage alarm is set to trigger at 10 VDC, and an over-voltage shutdown mechanism activates if the supply voltage exceeds 75 VDC.
There are three versions of the ISM-7401 available: the standard ISM-7401 with a single shaft, the ISM-7401D featuring a dual shaft, and the ISM-7401E which includes a dual shaft with a 1000-line incremental encoder. The device is engineered to cease operation at an over-temperature shutdown temperature of 85 °C (185 °F) to prevent damage, and it is optimal to use the stepper in environments where the ambient temperature does not exceed 40 °C (104 °F) unless additional cooling measures are provided.
