CN1 Control Outputs

Pin Signal
No. name
32 Z Phase Z output
33 ZCOM
34 ALM Alarm output
35 ALMCOM
7 BKIR Brake interlock output
8 INP Positioning completed
output
10 OGND Output ground common Ground common for sequence outputs (pins 7 and 8).
Note An open-collector output interface is used for pin-7 and -8 sequence outputs. (Maximum operating volt-
age: 30 V DC; maximum output current: 50 mA)
Function
Pulse string input terminals for position commands.
Line-driver input: 7 mA at 3 V
Maximum response frequency: 250 kpps
Open-collector input: 7 to 15 mA
Maximum response frequency: 250 kpps
Any of the following can be selected by means of a Pn200.0
setting: feed pulses or direction signals (PULS/SIGN); forward
or reverse pulses (CW/CCW); 90 ° phase difference (phase A/B)
signals (A/B).
Line-driver input: 7 mA at 3 V
Open-collector input: 7 to 15 mA
ON: Pulse commands prohibited and deviation counter cleared.
Note Input for at least 20 µ s.
Power supply input terminal (+24 V DC) for sequence inputs
(pins 14 and 18).
ON: Servo alarm status is reset.
Function
Outputs the Encoder's phase Z. (1 pulse/revolution)
Open collector output (maximum output voltage: 30 V DC max;
maximum output current: 20 mA)
When the Servo Driver generates an alarm, the output turns
OFF. Open collector output (maximum operating voltage: 30 V
DC; maximum output current: 50 mA)
Outputs the holding brake timing signals.
ON when the position error is within the positioning completed
range (Pn500).
