2-128 Parameter Descriptions
7000-TD002A-EN-P – September 2007
Tachometer Type [Tach Type]
Linear Number: 233
Default Value: None
Access Level: Basic
Read/Write: Read/Write when Stopped
This parameter specifies the type of tachometer or encoder installed. Warning: If tachometer type is set
to Single, the drive cannot determine the direction of rotation when the motor is coasting. If the direction
of rotation is not the same as the commanded direction, a flying start will not be successful.
The following types are available:
None No tach installed
Single Single output (non-directional)
Quadrature Quadrature outputs (directional)
Absolute Enc Absolute encoder
Sine-Cos Inc Not active
Sine-Cos Z Not active
Sine-Cos SSI Not active

Tachometer Pulses per Revolution [Tach PPR]
Linear Number: 234
Default Value: 1024 PPR
Minimum Value: 120 PPR
Maximum Value: 4096 PPR
Access Level: Basic
Read/Write: Read/Write when Stopped
This parameter specifies the number of pulses produced by the tachometer in one revolution. This
parameter is not used for absolute encoders.
Encoder Offset [Encoder Offset]
Linear Number: 644
Default Value: 0 deg
Minimum Value: 0 deg
Maximum Value: 360 deg
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the offset of the encoder. This parameter is required because an encoder is
used for both speed and position.
