• If a value out of the setting range is set, information of Electronic gear setting error is generated
(information code 2000h). If the main power supply and the control power supply is turned on
again or Configuration is executed in a state where information of Electronic gear setting error is
being generated, an alarm of Electronic gear setting error will be generated (alarm code 71h).
• If the resolution was changed after preset was executed in a state where the Home offset (607Ch)
is other than 0, execute preset again. When the Home offset (607Ch) is 0, it is no need to execute
preset again even if the resolution is changed. (The present position is calculated automatically.)
• When the TIM output is used in return-to-home operation or the like, set the resolution to be an
integral multiple of 50.
4-3 Wrap function
The wrap function is a function to automatically preset the position information of the present position when the
number of revolutions of the motor output shaft exceeds the set range. Setting the wrap offset can restrict the
operation area of equipment or control an index table with coordinates on the positive and negative sides.

4-4 Operating current and stop current
Set the base current rate (%) for the operating current and stop current in the Base current (4126h).
•
Operating current = Maximum output current × Base current (4126h) × Operating current (4120h)
• Stop current = Maximum output current × Base current (4126h) × Stop current (4128h)
•
Push current = Maximum output current × Base current (4126h) × Push current (4121h)
If the base current is set, the maximum output current of the driver can be changed. If a load is small
and there is an ample allowance for torque, the motor temperature rise can be suppressed by setting
a lower base current. However, excessively low base current may cause a problem in starting the
motor or holding the load in position. Do not reduce the base current any more than is necessary.
