Parameters for Motion Control
 Torque/Force Reference Monitor
This parameter reports the value of the torque reference.
The setting unit selected in bits C to F (Torque Unit Selection) of the OW03 setting
parameter is used for this parameter. In order to execute control correctly, it is necessary to set
bits C to F (Torque Unit Selection) in the OW03 setting parameter and the resolution of
the torque reference of the slave SERVOPACK. The following sections give the setting meth-
ods.
<Common Parameter No. 48 Setting>
Common parameter No. 48 (Torque Base Unit) can be set in one of two ways: either manually
or automatically. Both of these methods are described below.
• Manual Setting
If you set bit D (Torque Base Unit of SERVOPACK) in fixed parameter No. 1 (Function Selection
Flag 1) to 0 (Set by user), you must set common parameter No. 48 manually.
Note: If you use a servo amplifier from another company, set the value of n in the following formula.

To control appropriately, set common parameter No. 48 so that the following relationship holds.

• Automatic Setting
Set bit D (Torque Base Unit of SERVOPACK) of fixed parameter No. 1 (Function Selection Flag
1) to 1 (Set by system). The MP3000 will automatically set common parameter No. 48 (Torque
Base Unit) to -4.

Auxiliary Information
 Fixed Parameter Monitor
This parameter reports the data of the specified fixed parameter number when bit 5 (Read
Fixed Parameter) is specified for the OW0A setting parameter (Motion Subcommands).
