5.
As reported by THALL, is the Hall state sequence [1, 5, 4, 6, 2, 3, 1 ... ] as the
motor turns clockwise? (Clockwise means TPE is increasing; it is also the direction
the motor turns in DMODE13.)
IF NOT
: see Problem #4, below.
6.
Does TASX report a Hall fault each time the drive is enabled (DRIVE1), even
though the Hall state sequence is correct?
IF YES
: see Problem #4, below.
7.
Is the Hall fault intermittent? (Intermittent means the fault does not occur every
revolution.)
IF YES
: see Problem #5, below.
Possible Problems
:
#1: No Hall states are seen by the drive.
#2: Cable is not connected, or is connected incorrectly (miswired).
#3: DPOLE or DMEPIT is not set correctly.
#4: Either the motor wires or the Hall wires are connected incorrectly.
• Use Procedure I to fix this problem by changing the motor wires.
• Use Procedure II to fix this problem by changing the Hall wires.
#5: The Hall wires or the encoder wires may have loose connections, causing intermit-
tent faults.
Procedure I
:
Use this procedure to connect your
motor wires
to the Gem6K.
1.
Randomly connect two motor wires and slowly apply a positive voltage with respect
to the third. See the next drawing.
WARNING
This procedure could damage the motor. Slowly increase the voltage until
the motor moves. Do not exceed the rated current.
2.
If THALL reports back a 1, 2 or 4, change SHALL from either 0 to 1 or from 1 to 0.
After you change SHALL, reset the drive.
3.
Repeat step 1 until THALL reports a value of 6.
4.
The wire which is on the negative voltage or ground is motor wire W. The two wires
at the positive voltage are U and V.
5.
Now there are two possibilities:
5.1. Connect the motor wires to the terminals. Operate the drive in DMODE13. If
the motor does not turn in the clockwise direction, exchange motor wires U and V.
5.2. Put positive voltage on motor wire W together with either U or V and put
negative voltage or ground on the remaining wire. If THALL reports a value of 3, the
wire at the negative voltage is V. If THALL reports a value of 5, the wire at the
negative voltage is U.

Procedure II
:
Use this procedure to connect your
Hall wires
to the Gem6K.
1.
First operate the drive in DMODE13 and verify that the motor turns clockwise. If not,
swap any two motor wires.
