M7350-RSHI

Scaling: After the upper calibration and lower calibration points are entered, the M7350-RSHI automatically  scales the output position value for any point between the upper and lower safety limits. This saves the PLC from having to perform this computation.

Programmable Drift Limits: The M7350-RSHI constantly monitors the die position and deenergizes the fail-safe Drift Output if the measured die position moves outside the drift limits from the programmed position in either direction. The drift limit must be in the range: 0.000 to 0.250.

Programmable Backoff Distance: The Backoff Distance is that distance above the programmed position that the die will travel when it is being positioned from below the programmed position. The backoff distance value must be in the range 0 to 0.250.

Programmable Safety Limits: The Safety Limits define the upper and lower safe positions for die movement. If a Safety Limit is exceeded, either the Upper or Lower Safety Output will be deenergized.

Die Setup Storage: Variables for 500 single-action or dual-action dies can be preprogrammed and stored for later use. During a die change-over, the the Remote Enable (RE) Input allows the operator to select any one of 32 setups (Quantum-only). The PLC can access all 500 setups via the backplane. The operator can enter either a particular die number or die name to initiate the automatic die positioning sequence. The M7350-RSHI monitors the die position and provides this information to the PLC so it may control adjustment of the shut-height to the preprogrammed position.

Resolver RL210
Position information is provided by a resolver (AVG Autotech's dual resolver, RL210 with 128:1 gear ratio, or equivalent). The resolver is mounted to the Press Shut-Height Adjustment Drive Train (through some gears, if required).
