10.6 Drive Specifications
Note:
• To get the OLV specifications, do Rotational Auto-Tuning.
• To get the longest product life, install the drive in an environment that meets the necessary specifications.

•
OLV: 1:100
•
OLV/PM: 1:10
•
AOLV/PM: 1:100 (when high frequency injection is enabled)
•
EZOLV: 1:10
Zero Speed Control
Possible in these control methods:
• AOLV/PM
Torque Limits
Parameter settings allow different limits in four quadrants in these control methods:
• OLV
• AOLV/PM
• EZOLV
Acceleration and
Deceleration Times
0.0 s to 6000.0 s
The drive can set four pairs of different acceleration and deceleration times.
Braking Torque
Approximately 20%
Approximately 125% with a dynamic braking option
•
Short-time average deceleration torque
Motor output 0.1/0.2 kW: over 150%
Motor output 0.4/0.75 kW: over 100%
Motor output 1.5 kW: over 50%
Motor output 2.2 kW and larger: over 20%, Overexcitation Braking/High Slip Braking allow for approximately 40%
WARNING!
Set L3-04 = 0 [Stall Prevention during Decel = Disabled] when you operate the drive with:
• a regenerative converter
• regenerative unit
• braking resistor
• braking resistor unit.
If you set the parameter incorrectly, the drive can decelerate for too long and cause serious injury or death.
Note:
• Short-time average deceleration torque refers to the torque needed to decelerate the motor (uncoupled from the load) from the rated speed to zero.
Motor characteristics can change the actual specifications.
•
Motor characteristics change the continuous regenerative torque and short-time average deceleration torque for motors 2.2 kW and larger.
