1. Never touch the connection terminal of drive as the terminal has high
voltage.
Otherwise, danger of electric shock would be caused.
2. Before electrifying, please install the terminal enclosure reliably, and must
cut off the power before disassembling the enclosure.
Otherwise, danger of electric shock would be caused.
3
Laypeople are not allowed to maintain and check.
Otherwise, danger of electric shock would be caused.
Warning
1.
As CMOS integrated circuit is mounted on keyboard plate, control circuit
plate, driving circuit plate, please pay special attention when using.
Once the circuit plate is touched by finger, the integrated chip on circuit plate
would be damaged for electrostatic induction.
2.
In electrifying, never change the connecting wire or disassemble the
connecting wire of terminal.
In running, please never check the signal. Otherwise, the equipment would
be damaged.
1.3 Attentions of use
Please pay attention following points when using EXPERT series drive.
1.3.1 Constant-torque and low-speed running
In case that the drive with common motor runs at low speed for a long time, the life
of motor would be affected for the poor heat radiation. So if it is needed low-speed &
constant-torque long time running, professional drive must be selected.
1.3.2 Confirmation of motor insulation
When using EXPERT series drive with motor, please check up the insulation of
motor to protect equipment. In addition, if the motor is used in the harsh environment,
it is very necessary to check up the insulation of motor regularly, so as to protect the
safety of system.
1.3.3 Negative-torque running
In the occasions with strict requests for motor acceleration/deceleration time , the
drive would generate over current or over voltage fault and it would trip, in case of this,
a braking resistor shall be mounted.
1.3.4 Mechanical resonance point of load device
In the certain output frequency range, the drive is likely to meet the mechanical
resonance point of load device, if that, the jumping frequency must be set to avoid this
point.
1.3.5 Capacitor or pressure sensitive element that improves power factor
If there is a capacitor or varistor for lightning protection that improves power factor
