11.1 Prepare for a test run in AUTO mode by performing these steps.
AUTO mode operation operates the motor by providing the Z1000U Bypass with customer supplied, remote RUN and Speed Reference
commands. Items a. thru e. below are required to operate the Z1000U bypass in AUTO mode:
a. RUN Command (AUTO): RUN command, customer supplied. (STEP 5.1.a)
b. Interlock circuits: 2 each, customer supplied. (STEPS 5.1.b and 5.1.c)
c.
Frequency Reference (AUTO): Reference source, customer supplied. (STEP 7.5)
d. Common parameters are programmed. (STEP 8)
e. Motor rotation direction in DRIVE and BYPASS operation modes are verifi ed. (STEP 9)
11.2 Confi rm these remote AUTO circuits are connected to the Z1000U Bypass to prepare to
perform a test run in AUTO mode. AUTO circuits are customer supplied.
