Symbol
• If COM- is opened when the movable part of the
CWL
machine has moved to CW exceeding the limit,
the motor does not generate torque.
• If the COM- is opened when the movable part of
CCWL
themachine has moved CCW exceeding the
limit, the motor does not generate torque.
• When Pr04 (Overtravel Limit Input Disabled) = 1,
CWLand CCWL inputs are disabled. The default
is "Disabled" (1).
• The dynamic brake can be made operable during
CWL/
CCWL inputs valid. Use Pr66 (Dynamic Brake
Inactivation at Overtravel Limit) to make the
dynamic brake operable. The default is to allow
the dynamic brake to operate. (Pr66 value is 0.)
Symbol
• This is the input terminal for command pulses.
PULS1
The maximum allowable input frequency is 500
kpps for line amplifier input and 200 kpps for
PULS2
open collector input. The amplifier is the high-
speed photocoupler of TOSHIBA TLP554 or
SIGN1
equivalent.
• The input impedance of PULSE and SIGN
SIGN2
signals is 220Ω.
• Command pulses can be input in three different
ways. Use Pr42 toselect one of the following.
(See App.26.)
1) Quadrature (A and B) input
2) CW (PULSE)/CCW (SIGN) pulse input
3) Command pulse (PULS)/Sign (SIGN) input
