frequently due to frequent starts and

must be increased, it is necessary to use an optional

2. I f Pr.30 = 0, Pr.70 is not displayed. If Pr.30 = 0, the brake duty will be 3 %
3. If the set value for Pr.70 should be increased, the value must
be
smaller than the
permissible brake duty ratlo (refer to page 94) of the external brake resistor. (MRS

4. Brake resistor cannot be connected to 0.1 K and 0.2K. Because they have no brake
transistor.

CAUTION
A
Do not set the brake duty above the permissible value of the brake resistor used, otherwise,
overheating may occur.
