codes
Dynamic Brake Operated at main power OFF, servo alarm or overtravel.
External Regenerative Unit Required when exceeding the allowable load inertia
Overtravel Dynamic brake stop at P-OT or N-OT or deceleration stop
Protective Functions Overcurrent, grounding, overload, overvoltage, overspeed, overrun prevention, origin error, CPU
error, encoder error, overflow
Indicators
Alarm and power LEDs
Programming panel is available as an option
Others Brake interlock signal output, reverse run connection, JOG run, electronic gear, auto-tuning

1
Allowable load inertia ranges require no optional external regenerative unit. Values
are 30 times the moment of inertia for 30 W (0.04 HP) to 200 W (0.27 HP) Servomo-
tors, and 20 times for 400 W (0.53 HP) and 750 W (1.01 HP) Servomotors. If load iner-
tias exceed these ranges, restrict the operation or use a regenerative unit.
*
2
Supply voltage should not exceed 230 V + 10% (253 V) or 115 V + 10% (127 V). A
step-down transformer is required if the voltage should exceed these values.
*
3
Use within the ambient temperature range. When enclosed in a box, the internal tem-
peratures must not exceed the ambient temperature range.
*
4
N is the number of encoder pulses.
