Pulse Prohibition Input (IPG)
Pin 33: Pulse prohibition input (IPG)
This is the allocation at default setting. However, Command Pulse Prohibition Input (Pn518) is
set to disable (set value: 1). To use this, change Pn518 to enable (set value: 0). You can
change the functions for input terminals (CN1 to 8, 9 and 26 to 33) according to the settings of
Input Signal Selection 1 to 10 (Pn400 to 409).
You can only allocate the pulse prohibition input (ECRST) to pin 33 (SI10). Allocating this input
to any other terminal generates a pulse prohibition input allocation error (A337).
Function
You can use this input to forcibly stop the command pulse input.
When this input is ON, the driver ignores the command pulse input and does not count pulses.

Pin 33: Internally set speed selection 1 (VSEL1) Pin 30: Internally set speed selection 2
(VSEL2)
Pin 28: Internally set speed selection 3 (VSEL3)
This is the allocation at default setting. However, Command Speed Selection (Pn300) is set to
disable (set value: 0). To use this, change Command Speed Selection (Pn300) to enable (set
value: 1 to 3). You can change the logics and allocations for input terminals (CN1 to 8, 9 and
26 to 33) according to the settings of Input Signal Selection 1 to 10 (Pn400 to 409).
Function
Perform speed control according to the internal speed set value in the parameter.
You can select from up to 8 internal speed set values.
Pn300 set value
To use the internally set speed, use the zero speed designation input (VZERO) as contact b.(If
this is OFF, the speed command becomes 0.)The zero speed designation input (VZERO) is
set to disable (set value: 0) by default. To use this, change Zero Speed Designation Selection
(Pn315) to enable (set value: 1 to 2).
(If the zero speed designation input is not used, the motor turns at No. 1 Internally Set Speed
(Pn304) when the servo turns ON.)
