Start-Up

Configuration

To configure the operation of the OTAC-01 module:
1. Power up the drive.
2. Use the control panel on the drive and set the parameters described
below.
Operating Data
The following parameters provide feedback from the encoder. The drive
sets the parameter values based on measurements or calculations. You
cannot set these values directly, but you can use Group 50 parameters
to control mechanical angle and revolution data.
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 starts at zero on power-up and changes to 1 only if:
• Parameter 5010
• An encoder Z-pulse has been detected.
