*
When a fixture, heavy enough to pull the press ram down when the servo is not running, is
attached to the press ram use “Servo On” to monitor when to engage/disengage the brake
(maintenance lock). When “Servo On” signal goes high (On) release (disengage) the brake.
*
Under normal circumstances, the brake (maintenance lock) can be engaged/disengaged by wiring
it directly to the “Control Power” circuit; only engaging (locking) on loss of Control Power.
Unless instructed by FEC, System Parameter 00-36 should always be configured for
“Dynamic Hold”.
Setting the “Dynamic Hold” configuration allows the servo motor to
dynamically hold the press ram when stopped. Setting System Parameter 00-36 to “Off” forces
the Maintenance Lock (when equipped) to hold the press ram when the servo stops.
The maintenance lock should be used for maintenance purposes only, not for control.
Using the maintenance lock to control stopping of the press ram will decrease the life of
the lock unit dramatically.
This circuit is shown for reference only and does not guarantee the safe operation
of this press. Safety measures must be examined for each application.
