ACH550-UH User's Manual
Code Description
0146
MECH ANGLE
Defines the motor shaft's angular position to about 0.01° (32,768 divisions for 360°). The position is defined as 0 at
power up.
During operation the zero position can be set by:
• A Z-pulse input, if parameter 5010
• Parameter 5011
• Any status change of parameter 5002
0147
MECH REVS
A signed integer that counts full revolutions of the motor shaft. The value:
• Increments when parameter 0146
• Decrements when parameter 0146
0148
Z PLS DETECTED
When a Z-pulse defines the zero position, the shaft must pass through the zero position to trigger a Z-pulse. Until
then, the shaft position is unknown (the drive uses the shaft position at power up as zero). This parameter signals
when parameter 0146
• Parameter 5010
• An encoder Z-pulse has been detected.
0150
CB TEMP
The temperature of the drive control board in degrees C.
Note! Some ACH550 drives have a control board that does not support this feature.
These drives always show a fixed value of 25.0 degree C.
