Precautions during Use
Pay attention to the following precautions during use of this module
(1) Installation site/storage
Avoid installing or storing the pulse output module in the following locations:
1. Location subject to the direct sunlight
2. Locations outside of the ambient operating temperature range of 0 to 55°C and storage range
of -20 to +70°C
3. Locations outside of the ambient relative humidity of 35 to 90%
4. Locations subject to sudden temperature changes that might cause condensation
5. Locations subject to corrosive gases or flammable gases
6. Locations subject to direct vibration or impact
(2) Installation
1. Before removing or attaching the rack panel, turn the PC OFF.
2. Firmly tighten the fastening screws of this module.
(3) Wiring
1. Avoid wiring input, output and power leads near to and in parallel with heavy-current lines and
power lines.
2. To prevent damage to machinery and accidents to personnel, assemble an external emergency
stop circuit, interlock circuit or other means outside of the pulse output module, and integrate a
stop output for the JW50H/70H/100H.
(4) Use
1. Before turning the switch ON and OFF, turn the PC OFF.
Otherwise, the pulse output module may malfunction.
2. On JW50H/70H/100H mounted with this module, be sure to set the I/O addresses of the control
module by optional I/O registration. (I/O addresses cannot be set by automatic I/O registration.)
(Reason) Though this module is the special I/O module for the JW50H/70H/100H, it differs from
regular special I/O modules in that 256 bytes of special I/O data registers area is
occupied.
3. Be sure to set the JW50H/70H/100H scan time to 2 ms or more. If the scan time is set to a lower
value, data sometimes cannot be transferred to this module.
(For details on setting the scan time, →see the JW50H/70H/100H Programming Manual.)
4. This module cannot be used (mounted) on the JW50H/70H/100H remote I/O slave module.
5. When the JW50H/70H/100H is turned OFF, the data on this module is overwritten. Accordingly,
after writing block data, be sure to save the new data to flash ROM (for backing up data) by the
block data save relay.
6. The housing of this module is provided with ventilation holes to prevent the inside of this module
from heating up. Do not block these ventilation holes or block the flow of air into and out from these
holes.
7. If you detect any malfunction or abnormality () with this module, immediately stop use, and contact
your dealer.
(5) Work safety during operation (
→→
→→
→See the figure on the following page.)
• Provide a safety fence around robots.
• Provide a plug for entry/exit on the safety fence, and provide a structure so that robot operation
stops when the safety fence door is opened when a worker enters the area inside the safety fence.
• Provide a portable plug on the safety fence so that robot operation stops when that plug is ex-
tracted, and robot operation stays stopped even if a worker enters the area inside the safety fence
and closes the safety fence door still holding the plug.
• Provide a receptacle for on-site work for operating the robot inside the safety fence at the worker's
discretion. The robot operates by inserting the portable plug into this receptacle. When performing
teaching, for example, inside the safety fence to operate the robot, make sure that the worker is
outside of the robot's operation envelope.
