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.
Item
• V/f Control
• Open Loop Vector
Control Methods • PM Open Loop Vector
• PM Advanced Open Loop Vector
• EZ Vector Control

Main speed frequency reference: -10 Vdc to +10 Vdc (minimum 15 kΩ), 0 Vdc to 10 Vdc (minimum 15 kΩ), 4 mA to 20 mA (250 Ω), 0 mA to 20 mA (250 Ω)
Frequency Setting
Signal
Main speed reference: Pulse train input (maximum 32 kHz)
• V/f: 150%/3 Hz
• OLV: 150%/1 Hz
• OLV/PM: 100%/5% speed
• AOLV/PM: 100%/0 min
Starting Torque
• EZOLV: 100%/10% speed
Note:
Correctly select the drive and motor capacity for this starting torque in these control methods:
• OLV
• AOLV/PM
• V/f: 1:40
• OLV: 1:100
Speed Control Range
• OLV/PM: 1:10
• AOLV/PM: 1:100 (when high frequency injection is enabled)
• EZOLV: 1:10
Possible in AOLV/PM control methods.
Zero Speed Control
You can use parameter settings for different limits in four quadrants in these control methods:
• OLV
Torque Limits
• AOLV/PM
• EZOLV
0.0 s to 6000.0 s
Acceleration and
Deceleration Times
The drive can set four pairs of different acceleration and deceleration times.
Approximately 20% without a resistor
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:
Braking Torque
• 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 necessary torque 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.
