Table 4: EOP Table for HR Motors Driven by the AB51 Driver
(Reduced LUT).
Note:
In the Brake_Off Mode the full advantage of the AB5 driver is enabled giving a linear
◘
response, best tracking and low velocity performance. Using this mode, the motor
operates continuously, even at “0” command and special attention must be given to
maintain the work regime within the permitted "Duty Cycle" and "Maximal Continuous
Operation Time” (refer to Table 3 and Table 4). Once the operation time has reached the
"Maximal Continuous Operation Time”, even at Brake_Off Mode without motion (!) the
driver must be disabled to allow the motor to cool down for at least 400 seconds in air
and 700 sec in vacuum environment.
