Item Specification
Speed Control Range
• V/f: 1:40
• CL-V/f: 1:40
• OLV: 1:200
• CLV: 1:1500
• AOLV: 1:200
• OLV/PM: 1:20
• AOLV/PM: 1:100 (when high frequency injection is enabled)
• CLV/PM: 1:1500
• EZOLV: 1:100
Note:
• Set n8-57 = 1 [HFI Overlap Selection = Enabled] for this Speed Control Range in AOLV/PM. When you use a non-Yaskawa PM motor, do Rotational
Auto-Tuning.
• Speed control range of 1:100 for AOLV/PM is Instantaneous operation range. Correctly select the drive and motor capacity for continuous operation.
Zero Speed Control
Possible in these control methods:
• CLV
• AOLV/PM
• CLV/PM
Torque Limits
Parameter settings allow different limits in four quadrants in these control methods:
• OLV
• CLV
• AOLV
• AOLV/PM
• CLV/PM
• EZOLV
Accel/Decel Time
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 0.4/0.75 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%
• Continuous regenerative torque: Approximately 20%. Dynamic braking option allows for approximately 125%, 10%ED, 10 s
WARNING
Set L3-04 = 0 [Stall Prevention during Decel = Disabled] when you operate the drive with:
• a regenerative converter
• regenerative unit
• braking 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:
• Models 2004 to 2138 and 4002 to 4168 have a braking transistor.
• 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.
V/f Characteristics
Select from 15 pre-defined V/f patterns, or a user-set V/f pattern.
