Indicators Power (green LED) and status/alarm (red, 7-segment LEDs)
Digital operator: status/alarm (red, 7-segment LEDs ×5)
Others Torque control, zero clamp operation (position loop stop}, soft start/stop, speed coincidence,
brake interlock signal output, reverse run connection, JOG run, auto-tuning
* 1 Allowable load inertia ranges require no optional regenerative unit (applicable to
200V 30W to 200W) or external regenerative resistor (applicable to 100V 200W,
300W or 200V 400W, 750W). Values are when motor speed is 3000r/min max. If load
inertias exceed these ranges, restrict the operation or use a regenerative unit (appli-
cable to 200V 30W to 200W) or external regenerative resistor (applicable to 100V
200W, 300W or 200V 400W, 750W).
For details, refer to 5.3.5 Load Inertia.
* 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 The lowest speed of the speed control range is the speed at which the motor does not
stop under 100% load.
* 5 Speed regulation is defined as follows:
Speed regulation =
No-load-speed – Full-load-speed
Rated speed
× 100%
The motor speed may change due to voltage variations or amplifier drift and changes
in processing resistance due to temperature variation.
These ratios of the speed changes to the rated speed represent the speed regulation
due to voltage and temperature variations.
* 6 N is the number of encoder pulses.
* 7 Base mount can be available as an option (DR2-jjY7).
* 8 Open collector output can be available as an option (DR2-jjY1).
* 9 Values in parenthesis show SGMP type Servomotor.
