Standard Models and Specifications
Note 2. With the default allocation, the function for pin 41 is changed to MING, PLOCK, TVSEL, RDIR,
or IPG according to the Pn000.1 (control mode selection) setting and the control mode in op-
eration. For details, refer to 4-4-3 Important Parameters.
D Forward Drive Prohibit (42: POT)
Reverse Drive Prohibit (43: NOT)
These two signals are the inputs for forward and reverse drive prohibit (overtravel). When they are
input, driving is possible in the respective direction. When driving is prohibited, movement will stop
according to the settings of Pn001.0 and Pn001.1. Refer to the diagram below.) Alarm status will not be
generated at the Servo Driver while driving is prohibited
Note This is the default allocation. For either signal, the drive prohibition is normally disabled. This set-
ting can be changed by Pn50A.3/Pn50b.0. Input terminal selections (CN1 pins 40 to 46) can be
changed by means of Pn50A.0 (input signal selection mode).
Stopping Methods when Forward/Reverse Drive Prohibit is OFF
POT (NOT) is OFF
Note 1. The position loop will not operate for position control when stopping in this mode.
Note 2. When torque control is being used, the stopping method is determined by Pn001.0 setting.
(The Pn001.1 setting is irrelevant.)
D Alarm Reset (44: RESET)
This is the external reset signal input for the servo alarm. Remove the cause of the alarm and then
restart operation.
Caution Turn OFF the RUN command before inputting the reset signal. It can be dangerous to input
the reset signal while the RUN command is ON.
Note This is the default allocation. The input terminal allocations (CN1 pins 40 to 46) can be changed by
setting Pn50A.0 (input signal selection mode) to 1. The RESET signal is allocated by Pn50b.1.
D Forward Rotation Current Limit (45: PCL)
Reverse Rotation Current Limit (46: NCL)
These two signals are inputs for limiting the forward and reverse output current (output torque).
When these signals are input, the output torque in the respective direction of rotation is limited by the
settings of Pn404 (forward rotation external current limit) and Pn405 (reverse rotation external current
limit).
