System Design and Installation
Note If the dynamic brake is stopped at a speed higher than the speed specified above under Applica-
For Servomotors of 1.5 kW or less, observe the following precautions if there is a possibility of the power
being turned ON while the Servomotor is rotating.
In Servomotors of 1.5 kW or less, the dynamic brake circuit uses a relay. Normally, if an alarm occurs
while the Servo is OFF, the dynamic brake operates according to the function selection application
switch (Pn001.0, 1) when drive prohibition is being input. At 1.5 kW or less, however, the dynamic brake
operates regardless of this setting even if the main circuit power supply or the control power supply is
OFF.
Current flows to the relay while the dynamic brake is operating. If 2 (Stop Servomotor by free run) is
selected for the function selection application switch (Pn001.0: Stop selection for alarm generation with
Servo OFF), the relay turns OFF when the power is turned ON again.
If the power is turned from OFF to ON while the Servomotor is rotating, the relay operates while current
is flowing to it. This may cause the relay contacts to fuse.
For Servomotors of 1.5 kW or less, if there is a possibility of the power being turned ON during Servomo-
tor rotation, either set 0 (Stop Servomotor by dynamic brake) for the function selection application
switch (Pn001.0: Stop selection for alarm generation with Servo OFF) or make sure that the power will
not be turned ON until the Servomotor has stopped.
