A holding lock is a lock used to hold the position of the movable part of the machine when the DRIVER is
turned OFF so that movable part does not move due to gravity or external forces. Holding locks are built into
servomotors with locks.
The holding lock is used in the following cases.

The brake built into the servomotor with brakes is a de-energization brake, which is
used only to hold and cannot be used for braking.
• Use the holding lock only to hold a stopped servomotor.
There is a delay in the braking operation. Set the following ON/OFF timing.
