including the host device.

 

offset

[0]

 

• Offset volume will be approximately 0.3mV per a set value “1”.

To adjust offset, there are 2 ways of (1) manual adjustment and (2) auto- matic adjustment.

1) Manual adjustment

• When you make offset adjustment with the driver only:

Using this parameter, set a value that prevents the motor from rotat- ing, after you have correctly input 0V in torque command input (SPR/TRQR) (or connected to signal ground).

When the host device establishes a position loop:

With servo locked, using this parameter, set a value so that deviation pulse will be zero.

2) Automatic Adjustment

For details on operating instructions in automatic offset adjustment mode, refer to “Details of Execution Display of Auxiliary Function Mode” of Preparations volume on page 66.

When you execute automatic offset adjustment, result will be reflec- ted in this parameter Pr52.

Pr56 is a value of speed limits in torque control mode.

You should set this parameter in a range of rotational speeds of the motor to be used.

57

JOG speed set up 0 – 500 r/min The parameter directly sets JOG speed in JOG run in “motor trial run

[300]mode” in terms of [r/min].

For details on JOG function, refer to “Trial Run (JOG)” of Preparations vol- ume on page 68.
