the AMAT 0190-07452 is an IP-Stepper Dual Stepper Motor Motion Controller IndustryPack. The IP-Stepper provides two independent motion control channels for stepper systems. Each channel consists of a Nippon Pulse Motor PCL-240MK programmable high speed pulse generator and a U.S. Digital LS7166 Encoder Interface Chip. The LS7166 provides additional quadrature decode capability for programmable way-point triggering, indexing, travel limiting and closed loop motion control.
Every IP contains an ID PROM, whose size is at least 32 x 8 bits. The ID PROM aids in software auto configuration and configuration management. The user's software, or a supplied driver, may verify that the device it expects is actually installed at the location it expects, and is nominally functional. The ID PROM contains the manufacturing revision level of the IP. If a driver requires that a particular revision be present, it may check for it directly.
The location of the ID PROM in the host's address space is dependent on which carrier board used. Normally for VMEbus carriers the ID PROM space is directly above the IP's I/O space, or at IP-base + $80. Macintosh drivers use the ID PROM automatically. RM1260 address may be derived from Figure 14 below by multiplying the addresses given by two, then subtracting one. RM1270 addresses may be derived by multiplying the addresses given by two, then adding one.
IndustryPacks were conceived and engineered for rugged industrial environments. The IP-stepper is constructed out of 0.062 inch thick FR4 V0 material.
The IndustryPack connectors are keyed, shrouded and gold plated on both contacts and receptacles. They are rated at 1 Amp per pin and a minimum of 200 insertion cycles. These connectors make consistent, correct insertion easy and reliable.
The IP is secured to the carrier with four M2 metric stainless steel screws. The heads of the screws are countersunk into the IP. The four screws provide significant protection against shock, vibration, and incomplete insertion. For most applications they are not required.
The IndustryPack provides a low temperature coefficient of 0.89 W/°C for uniform heat. This is based on the temperature coefficient of the base FR4 material of 0.31 W/m-°C, and taking into account the thickness and area of the IP. This coefficient means that if 0.89 Watts is applied uniformly on the component side, that the temperature difference between the component and the solder side is one degree Celsius.
