在负载短路、绕组短路或失速的情况下电机，负载电流将尝试增加。如前所述如上所述，输出级的驱动电流被分流（将负载电流限制在1 A左右），导致输出舞台线性化。作为输出的结温级增加，热限制电路将变为操作，进一步降低驱动电流。负载电流（结温）是环境温度的函数温度、剩余驱动器的状态、电源电压和负载电阻。如果故障条件得到纠正，则输出驾驶员将恢复到正常饱和状态。UIOC和VMIC徽标是的注册商标VMIC。

In the event of a shorted load, shorted winding, or stalled
motor, the load current will attempt to increase. As described
above, the drive current to the output stage is diverted
(limiting the load current to about 1 A), causing the output
stage to go linear. As the junction temperature of the output
stage increases, the thermal limiting circuit will become
operational, further decreasing the drive current. The load
current (junction temperature) is then a function of ambient
temperature, state of remaining drivers, supply voltage, and
load resistance. If the fault condition is corrected, the output
driver will return to its normal saturated condition.

PHYSICAL DESCRIPTION
The VMIVME-2511 Programmable I10 Board consists of VMEbus compatibility
logic, interrupt control logic, and I10 control logic associated with the parallel
interfaceltirner modules.
The VMEbus compatibility logic contains address decoding logic and data
transfer control logic allowing VMEbus write and read data transfers.
Interrupt control logic which utilizes the Motorola MC68153 BIM allows port and
timer interrupts from each parallel interfaceltimer. The interrupt requests to the CPU
are issued by the MC68153 when requested to do so by the parallel interfaceltimer
(68230).
