■
Acceleration/Deceleration Times
Acceleration and deceleration times are affected by
how much torque the motor generates, the load torque,
and the inertia moment (GD
2
/
4). Set a longer accel/
decel time when Stall Prevention is enabled. The accel/
decel times are lengthened for as long as the Stall
Prevention function is operating. For faster acceleration,
increase the capacity of both the motor and the drive.
For faster deceleration, use a dynamic braking option or
a power regenerative unit.
General Handling
■
Electrical Shock Hazard
Failure to comply may result in death or serious injury.
Do not allow unqualifi ed personnel to perform work on the
drive. Installation, maintenance, inspection, and servicing
must be performed only by authorized personnel familiar
with installation, adjustment, and maintenance of AC drives.
■
Wiring Check
Never short the drive output terminals or apply voltage to
output terminals (U/T
1, V/T2, W/T3), as this can cause
serious damage to the drive. Doing so will destroy the
drive. Be sure to perform a fi nal check of all sequence
wiring and other connections before turning the power on.
Make sure there are no short circuits on the control
terminals (
+
V, AC, etc.), as this could damage the drive.
Retighten the screws for the wiring terminals periodically.
■
European Terminal
･
For European terminals, do not shake the wires
excessively or pull on the wires too much.
･
When connecting uninsulated wire and when crimping
wire to the solderless terminal, do not let the wire
protrude past the conductor section. Pay close attention
to this because it could cause a short circuit.
･
Check for any unsuitable wire size connections.
･
Righten at the specifi ed torque.
■
European Terminal Wiring Work
Heed the following points. Follow the procedure in the
manual concerning all points except the following.
･
Use the torque driver or a torque wrench and ratchet.
The tip of a straight-edge screwdriver or a hex socket
tool is required for wiring the European terminal.
･
Wiring tools can be purchased from Yaskawa. Contact
Yaskawa. The torque wrench should be supplied by the
customer.
･
To replace a previous model, the wires that are used
may be partially out of connection range. Contact
Yaskawa beforehand about the available wire gauges.
■
Wiring Using Closed-loop Crimp Terminals
Wrench-type or closed-wrench type tools cannot be used
with drives with catalog codes of CR
70
□
2215 and above
or
4180 and above. Make sure to always use socket-type
tools. Use only sockets with a depth of
30 mm or more.

■
Magnetic Contactor Installation
Avoid switching a magnetic contactor on the power
supply side more frequently than once every
30 minutes.
Frequent switching can cause damage to the drive.
■
Keypad
[microSD card]
･
The SD card supports microSD, and microSD HC with a
capacity of up to
32 GB.
･
Plug in and remove the microSD card after turning off
the power supply for the drive. Do not remove the
microSD card or de-energize the keypad when
accessing the microSD card. This may cause data loss
and failure.
･
If there are many fi les and folders on the SD card or if
the free space on the microSD card is low, the SD card
may not run properly.
[Connection via USB]
･
Use a miniUSB cable. The USB connection between the
PC and keypad is not possible while the drive and
keypad are connected. First remove the keypad from
the drive and then connect with the PC.
･
While connected to the USB, it is not possible from a PC
to access the fi les on a microSD card that is inserted.
■
Inspection and Maintenance
After shutting off the drive, make sure the CHARGE light
has gone out completely before preforming any inspection
or maintenance. Residual voltage in drive capacitors can
cause serious electric shock.
The heatsink can become quite hot during operation, and
proper precautions should be taken to prevent burns.
When replacing the cooling fan, shut off the power and
wait at least
15 minutes to be sure that the heatsink has
cooled down.
